Ok, well what i want to do is to give the subjects the opportunity to repeat the trial if they feel like they have not understood the text that is presented within the trial. so what i wish to happen is that if the subjects press one of the shift keys, those responses should be logged as a response in the data file. however, if they press the space bar, the trial should start again from the beginning.
with the branch command i have built in, this does not work, inquisit tells me this: " Expression 'trial.a1.response' is invalid. The expression attempts to set the value of read-only property."
So what i am guessing is that the command for "when subject hits "57" " that i put in is wrong.
I hope that makes the problem clearer!
Thanks a lot!
