Hi,
I am testing a web experiment. I am using group assignment in the url (e.g., ?mygroup=1, ?mygroup=2, etc.). In the experiment I have 24 different groups, based on the group number the participants gets one of 4 experiments, and 1 of 24 variable assignments. The assignment to experiments works perfect, but the variable assignment seems to be random and does not correspond to the group number.
I've pasted the relevant parts of the script below. Can anyone tell me how I can get the variables element to work correctly?
Thanks,
Diane

If you want the <variables> assigned based on the groupnumber you pass in, you need to specify
<variables>
/ groupassignment = groupnumber
...
</variables>
just like you do in the <expt> elements. Otherwise <variables> will be assigned based on subjectnumber by default.
