SNGCHCFLD and PSHBTNFLD - Seems that nothing is selected

Hi!

I designed a window with a single choice list of 3 elements, and a button
"OK" at the bottom of the window. If the user clicks on an element of my
single choice list, everithing works fine. But if he positions the cursor on
an element of the list and then push the OK button, my program does not
receive any selection. I also tried to use the CHCCTL to get the selection
but it does not work if the user hightlights an element of my list and then
push the OK button...

Any suggestion to get the item that is highlighted when the user push the OK
button?

Here's a short piece of my display file code:

A                                      CHOICE(2 'Choice 2')
A                                      CHOICE(3 'Choice 3')
