Hi,



I just registered a web script and am having different people try it out on their computers. It works fine on mine, but crashes when other people try it.


I used web control version 4.0.2.0.



The crash happens just after the first block, which contains a surveypage I use as a consent form. 


This is the page & the block:  


<surveypage consent>
/ questions = [1=consent]
/showpagenumbers = false
/ showquestionnumbers = false
</surveypage>

<block consent>
/ trials = [1=consent]
/ preinstructions = (consent)
/ postinstructions = (consentok)
/ quit = [radiobuttons.consent.response=="0"]
</block>



The second block is variable based on the subjectnumber.


<variables>
/ group = (1 of 2)(block2=UUT; ...
/ group = (2 of 2)(block2=RAT; ...


Here are the two blocks. Nothing remarkable about them ...


<block RAT>
/ trials = [1-30 = noreplace (RATdifficultpage, RATeasypage)]
/ preinstructions = (RATintro1, RATintro2, RATintro3, RATintro4, RATintro5, RATintro6)
/ postinstructions = (RATend)
</block>


<block UUT>
/ trials = [1-4 = noreplace(UUTpage)]
/ preinstructions = (UUTintro1, UUTintro2)
/ postinstructions = (UUTend)
</block>



Both blocks don't use any files, so that doesn't seem the to be the problem.


We tried running the experiment with Firefox and Chrome with updated Java, both times it crashed.


Any ideas what could be the problem?



Thanks in advance,


Claire
