Hello all,

I want to use /iscorrectresponse to counterbalance which key to press on my trials. I have it currently set up as follows:

<trial practice_left>
/ pretrialpause = 300
/ validresponse = ("Q", "q", "P", "p")
/ iscorrectresponse = [(values.expcondition == 1 && trial.practice_left.response == "Q" || values.expcondition == 1 && trial.practice_left.response == "q")|| (values.expcondition == 2 && trial.practice_left.response == "P" || values.expcondition == 2 && trial.practice_left.response == "p")]

/ errormessage = (errormessage, 200)
/ responsemode = timeout (3000)
/ stimulustimes = [0=practicenames; 300 = eraser; 300= category_left]
/ posttrialpause = 300
</trial>

expcondition is defined globally as 0 but redefined onexptbegin as 1 or 2 (depending on the subject number).
The problem I am facing is that no matter what key I press, I always get the errormessage. I am new to Inquisit so I only half know what I am doing. I have tried several things to see where the problem lies (whether it is due to expcondition or whether it is due to using too many expressions), but nothing has worked so far.

Does anyone know where I am going wrong here?

Kind regards
