Pamela, thanks for the reply.

The code is something like..
LOCAL lnFormValue
DO FORM myForm TO lnFormValue
IF lnFormValue=lnAnotherValue... etc.


Problem update...

I have investigated the problem further and have now placed the same code in the click methods of both the toolbar close-button and a 'Close' button on the modal form itself.

IF _screen.activeform.queryunload()
_screen.activeform.release
ENDIF

When the form-button is pressed, the form closes and a value is returned to lnFormValue. When the toolbar button is pressed, the form closes, but no value is returned (if lnFormValue is not initialised, it doesn't even exist when control passes to the following line!) even though RETURN lnReturnValue is definitely executed in form.unload().

Any further ideas would be appreciated.

Regards,
Alan
