For example, there are is a feedback that have 5 questions (Q1, Q2, Q3, Q4 and Q5) and 5 choice (A1, A2, A3, A4 and A5). So, all the 5 choices will be available to the student for all the 5 questions. However, if the student select A3 for Q1, then, he will not be able to select A3 for Q2, Q3, Q4 and Q5. (One unique choice for each question.)
The reason for this new function is that currently there are other format such as the Multiple-Choice feedback (with either one OR multiple choice) but there isn't any feedback that have function like the one that I say above.
If anyone know of such plug-in that works like the above. Please kindly let me know. Thanks
For example if we asked this question: rate these 3 VLEs in order of preference, we would like it to be impossible to check radio button #2 for two VLEs.
Any ideas anyone?

I have the following algorithm for checking on the type of question which allow one unique selection in both row and column. There are as follows:
Teacher's View
[1] The program ask for how many answers there are.
[2] The program ask the user to enter the answers into the respectively answer box.
[3] The program ask for how many questions there are.
[4] If the number of questions is more than the number of answers, the program will notify the user that it is not possible! (If there are more questions than answers, then there will be questions without a unique answer... right?)
[5] The program ask the user to enter the questions into the respectively question box.
[6] The program prompt the user to save changes to current feedback format.
(The program will check if there are any duplicate answers. If there are, the program will stop the user to save the changes and notify he / she to enter unique answers)
Student's View
[1] The program will shows the questions and answers in the format like the picture that Joseph have show above.
[2] The program will wait unit the student click on the Submit button.
[3] If the student click on the Submit button, the program will check if there are any answers being repeated.
(Suppose that there are 3 questions and 4 answers, then there will be a question array variable of 3 and a answer array variable of 4. The program just need to ensure that there is no duplicate entry is the answer array variable. If there are, it will notify the student to resubmit again)
One last thing to note is that this type of feedback question format can be a stand-alone if it is too complicated or added together with other type of feedback question format.
I think the algorithm is still not yet perfect and need more refinement. If anyone got a better algorithm, please kindly address them in here. Thanks.
I am pleased to announce that I have solved this problem. The solution relies on some Javascript which, upon one of the radio buttons being clicked, verifies the checked value of the other buttons in the same column and, if any of those buttons had previously been checked, unchecks it.
I have implemented the solution in my proposed version 2 of the Questionnaire module, and it can be tested live on my test site. See login instructions etc. in this post. The questionnaire which features one question with this new system is in Topic 1, CMS Survey, Question 1: Psychologists have determined that certain colours etc.

I was not able to find the 'unique answer for each question' question format type in the v2 Questionnaire module that I download from your test site. Can briefly let me know how to create such question so that I can test on my own system. Thanks.
Tested Questionnaire module version: 2007010801
Tested on Moodle system version: 1.7.2
Please kindly let me know if there are any special settings required to solve the problems above. Thanks.
This feature is available in the latest version, available on my test site, dated 11:12 27/05/2007.
Joseph
I have download the file from your test site as shown in one of the diagram attached.
(However, there is one thing to note is that in the Moodle System, there is another way to look at the Questionnaire Module version, also shown in the diagram)
So, I was wondering whether where can I find the version for the Questionnaire Module that you mention?
After download the file, I try to test the Questionnaire ...... (continue on next thread because the pictures is too big to fit into this thread)

About version number. The version number displayed in Admininstration/Activities screen (as shown in your screen shot) is the MAIN VERSION NUMBER. This number only gets changed by the module maintainer for major changes. The date version number 2007010801 refers to Mike Churchward's january version. When I say "download the latest version v2", I refer to the latest files available on my test site. Today, for example, this means version dated 11:12 27/05/2007 (hh:mm dd/mm/yyyy).
The 'unique answer for each question' question format in Likert scales was introduced in one of the latest versions, so maybe you can't use it because you don't have the very latest version installed on your system.
If you try it on my test site, you will see that it does work as described.
Please note that I am now working in collaboration with Mike Churchward on this project and we are gradually integrating my changes into the version which is available through CVS and it is also available from the Moodle plugins page at http://moodle.org/mod/data/view.php?d=13&rid=84.
However, it will take us another few days to integrate my latest developments into it, so you'll have to be patient!
Joseph
I look forward to your latest developments especially the Likert scales, which I was not able to create one successfully at my local hosting using the copy that you mention. (download from your test site)
Also looking for the changes that I previously post in http://moodle.org/mod/forum/discuss.php?d=72481 in your latest developments.
Do hope to see your latest development copy in your test site so that I can do some testing and provide my suggestions and comments.
The file from the test site has the following status:
> File Size: 406,271 bytes
> Total Files: 129 Files
> Total Folders: 13 Folders
(Kindly let me know if the file does not have the correct file size.)
(By the way, I was wondering how to insert many pictures into Module Forum as it only allow one picture to be sent, ... and also whether can the size limit go up higher, probably about 500Kb?)
Problem [1]
Let's me continue explain the problem further, after download the Questionnaire from your test site and setup into the PC, I try to create a Questionnaire with the following settings (See picture). I still could not create the unique answer!
According to the help file, having the setting of Precision of 2 will create the Question with unique answer but however, it seem that it does not reflect in this copy.
So, I was wondering whether if the copy on the test site has been updated or if there are some settings that I have missed out. Please kindly advise me. Thank you.
