Tom,

Thanks for the advice. Interestingly enough, while it worked just
swell in my test workbook, it did not change anything in the
application I am working on and I am not sure what the fundamental
difference between the two is. I did note that in the test workbook,
all of the values must be initialized to false in order for the
buttons to function properly. If one is initialized to true and
others to false, a double click is necessary to change the selection
the first time. Once it has changed, behavior seems normal.

In my application:

If I show the form and move it to a location so that the linked cells
on the worksheet are visible, I observe the following behavior:

When all options are false, clicking on any option will change its
value to true, run the click event code, and change the appropriate
linked cell value to true. - OK

However....

if option 1 is true and I click on option 2, the following happens:

option 1's value changes to false, the radio button black dot is
cleared, and the linked cell's value is changed to false. option 2's
value is changed to true (msgbox option2.value code in click event),
but the option 2 radio button does not get it's black dot, nor does
the linked cell value on the worksheet change. If I click again on
option 2 (or click on any other option), the appropriate values are
set and the radio buttons are filled/unfilled appropriately.

Putting a Repaint in the click events of the option buttons had no
effect. Putting a Calculate in the click events of the option buttons
effectively negated the effects of any and all clicks (no buttons nor
values would change regardless of what was clicked)

Any suggestions?

Thanks,

-Will
