It sounds like you are trying to get the selection at
the wrong time. When an item is selected from a popup
trigger, your app receives a popSelectEvent. Then you
can use code like the following (in your
MainFormHandleEvent) to deal with it:
case popSelectEvent:
if ( eventP->data.popSelect.controlID ==
TwoSelect2PopTrigger )
{
if ( eventP->data.popSelect.selection == Whatever
)
// respond to selection of Whatever
