Possibly because (assuming from your variable name), SelectorTriggerID is
not a label control. Its a popup trigger control.
Try instead:
void UpdateTrigger(Word FieldNumber,char *NewString)
{
ControlPtr CtlPtr;
CharPtr Buf;
CtlPtr = (ControlPtr)GetObjectPtr(FieldNumber);
Buf = CtlGetLabel(CtlPtr);
StrCopy(Buf,NewString);
CtlSetLabel(CtlPtr,Buf);
CtlDrawControl(CtlPtr);
}
