Thank you Mike:
that was indeed the prob. i checked back the script and of course i turned back all the changes that i´ve made to it and everything works fine now. Great!. i used phpESP some time ago with standard distribution package and i remember that i had to change this lines for correct use of it. now with moodle you dont have to, its kind of confussive, anyways its part of the game-
using CVS is a solution, yes, i found a script on the net that enables you to add almost 512 colums of data. 256 in one excel sheet and the rest in another, its not a skillfull fix but but it its a workarround.
it would be great if someone with script knowledege could spare some ideas how to handle the survey/report.php to make long multichoice surveys data to be presented in rows rather than using the colums.
well...thank you for your support..
Adios,
Don Julix.
