Eric,
You'll probably have to use CtlSetLabel like this:
CtlSetLabel (GetObjectPtr (PopUpTrigger), ListOfNames[selection]);
Where "ListOfNames" is your string array of names, and "PopUpTrigger" is
whatever the name of the particular Trigger you want to change the label
of...
I think that'll accomplish what you want...
