Hi Edy
Thanks a lot for your reply.
I gave a lot of thought to my question during the week-end, and yes, you are right: It cannot be done.
I managed to solve the problem using event handlers and making the G and R buttons invisible if B3 is clicked, but visible if B1 or B2 is clicked.
Best Regards,
Leon
