Using multiple responses.xls files possible? (case 437)

[friescamp]

Hi,

in MediaLab v2010, I have programmed a game where participants can "buy" products, and they get a small reward upon making specific (preprogrammed) choices. Participants should also be able to see how much money they have left and how much rewards they received. To do this, I created a responses.xls file, which works nicely.

However, the problem: The price of the products participants buy, and the products for which they receive a reward, differs between conditions.
Thus: If in e.g., condition 1 the variable "choi1" (the first choice) gets the response "4" by a participant, then the money counter should e.g., distract 40 cents. In condition 2, this should be not 40 but e.g., 50 cents.
In total, participants make 50 of these choices.

I think the easiest solution would be to create multiple responses.xls files (e.g., called responses1.xls, responses2.xls, et cetera), and that MediaLab knows which xls. file to search for in every condition.

Does anyone know if this is possible, or knows of another solution?

Thanks very much in advance!
