Hi all

I have a form property lLastDOW = .NULL. the checkbox comes up with a Gray tick mark as expected. Now I click in the checkbox and THIS.VALUE = "0", another click THIS.VALUE = "1". I have tried to set VALUE to .F. in the properties sheet, but I still get character "1" or "0", not even numeric 1 or 0

How can I get the checkbox to be NULL at startup, when first clicked go from Gray to Ticked and THIS.VALUE = .T., second click become Un-Ticked and THIS.VALUE = .F., then subsequent click toggles .T. and .F.

Please advise.
