custom and html files' problem (case 16275)

[mayday]

Hi administrator and fellow medialab users

While running the experiment, i had met with two technical problems that i need help with.
1) I had inserted the slider file that i downloaded from medialab forum and used it in my experiment. There are script error that pop up and says "script has stop running. do you want to continue running the script?" at any random question that made use of the slider file. I need to end medialab and restart it in order to solve it, so that previous entries are all lost and participants had to do them again.

2) I had inserted one html file that involves participants getting a pop-up saying they have the wrong answer every time they submit their answer. There are three questions in a row that use this same html file. However sometimes after the first question, the participant see the screen suddenly change to one that displays all the files i have in that folder for that questionnaire.

By the way i am using Medialab 2008 version and the files i am using are zip inside for reference.
