How can I make my checkboxes to work together?

[caracena]

Hi all,

I have two checkboxes that came from one of my tables in a form... I want them to work together, meaning that when one is checked, the other one gets unchecked. I've tried changing these into radio buttons but nothing happens... they are not "grouped" and when editing my form, it doen't give me "group" burron in the toolbars.

Thanks in advanced,

Nevermind... I've found the Group Option field

Thanks!!
