experiment timer, or safe mid-experiment stop?

[Sam]

Hello, 

I found the above script for setting the Break State to be very helpful 
since I am currently trying to accomplish something similar. I have an IQ 
test that must advance to a feedback stage after 20 minutes if the 
questions haven't been completed. However, the way I implemented the above 
suggestion, it seems to wait until the end of the trial in order to 
terminate. Since subjects can take as long as they want on each trial, the 
trial duration is "infinite", so it's possible it could never exit until 
much later if they are just beginning one of the questions before the time 
runs out. Do you know if there is a way I can modify the script so that it 
would end the current trial as soon as the time limit is reached?

Thanks for your help, and I apologize if there is something very basic I 
have missed. I am somewhat new to programming in E-prime. 

Sam
