the first question is which version of Moodle and the Hotpot module are you using?
To get the results of a Find-It quiz (e.g. your "modified" quiz), you will need v2.1 of the HotPot module, which is included in Moodle v1.6
Moodle v1.5 comes with v2.0 of the HotPot module, but this cannot record the results of a Find-It quiz.
I tried your quizzes using Hotpot v2.1 (Moodle 1.6) on my testing server and they seemed to work OK. The results were recorded as expected.
Officially, Hotpot v2.1 is still in a developement stage, so it is not recommended for live Moodle sites, especially when there are many students and teachers. However, if your site has only a few classes and you are the only teacher, you could consider installing Hotpot v2.1, because it works with Moodle 1.5. Then you could start using Find-It quizzes today
You can download Hotpot v2.1 form the Moodle CVS depository, or from the following URL on my server:
