If you are using the form control option buttons then put them inside a
group box. All option buttons inside a group box are mutually exclusive.
If you are using the ActiveX option buttons then set the Groupname property
on each of the option buttons to the same value.

I need to set up 3 option boxes that are mutually exclusive.
When I click on one option box the other two should be unchecked
etc.etc.
How do I go about doing this - I had a look through the forum but I
can't seem to find a solution.

Thanks
