Terminate list at set time, even if current sample no completed.

[Kate Cox]

Hi I'm very new to eprime and have no script background so please be gentle 
:).

*What I'm trying to do:* present participants with a series of mathematical 
equations which they must answer, using the keyboard. They must answer as 
many equations as they can in 2 minutes. After 2 minutes the task will 
terminate (and go on to the next task) even if they are part way through 
giving an answer. The outcomes i'm measuring are accuracy, RT of correct 
responses and number of correct responses in the 2 minute time window.

*What is working and how I have it set up*: I have 300 potential equations 
in a list called "TrialList", which are presented on a TextDisplay. This 
works perfectly.
Answers typed on the keyboard are echoed on the screen and logged. When an 
answer is complete the participant presses ENTER and the the next equation 
in my list is shown. This works perfectly. 
In the TextDisplay properties, under the Duration/Input tab I have duration 
as infinite, timing mode as Event, the keyboard as the only device, 
allowable responses is any, time limit is same as duration and End action 
is terminate.
In the list properties, under the Reset/Exit tab I have set Exit List to 
"After 120 seconds"

*The problem: *I can't get the task to terminate at exactly 2 minutes. At 
the moment it appears to stop when the trial that is running at 2 minute 
mark is terminated (ie the participant presses enter).  For example if a 
participant starts an equation at 1:55 then the task won't stop at 2:00 it 
will wait until they submit their answer and that trial is terminated. As 
some of my participants aren't particularly fast to provide their responses 
this may end up being closer to 3 minutes than 2.  

I'm pretty useless with script but I've found the bit that refers to the 
termination settings and it looks like this:

Set TrialList.TerminateCondition = TimedMSecs(120000)
Set TrialList.ResetCondition = Samples(300)
TrialList.Reset

I've tried searching this group and the Eprime guide for the answers but 
can't find how to fix it. I know some people have mentioned some script 
that terminates at a particular clock setting  but my script seems to look 
different to theirs so I'm not sure how to implement it. Also this maths 
task is part of a larger battery of tasks so how a participant performs on 
earlier tasks will determine where the running clock is when they get up to 
the maths problems (ie a participant who is faster at earlier tasks may 
start the math task at the 5 minute mark and someone who is slower might 
start it at the 7 minute mark, so the running clock will be different 2 
minutes into the math task).

I hope all this makes sense. Any help would be hugely appreciated.

thank you in advance
Kate
