time limit for task

[David Moore]

Hi Mich,

Thank you very much for your help. There are two small problems that I am 
still having. I have the experiment set up with two procedures coming from 
one this one running one task and one running the other. After the end of 
each trial the following script is run

If Decresp.resp= 1 then goto Label1
If Decresp.resp= 2 then goto Label2

This either takes them back to before the trial again to stay put of ends 
the trial and starts the other task. Therefore by by setting the end time 
as 10 minutes in the overall list it will only exit after the participant 
chooses to change the task. I was therefore wondering if there was some 
script that can end it more immediately at 10 minutes.

Also I have put in the script for the time however it does not seem be 
displayed on the slide I have put a text display with [SecondsLeft] in it 
however is says there is no such attribute.

Thank you again
David
