Interrupting a trial (was Starting where I left off

Tony,

Thanks for your response.  I tried this and it worked just fine.   However,

That is exactly what I want to do.  If a trial is in progress when the 30-second
time limit is up, I'd like to be able to stop the trial and go on to the next
procedure.  Any advice?

Stephan,


Give that a try and see what secondary problems you run into.
