Sorry, I didn't see it there. Anyway, you shouldn't be doing a REPLACE on MyCfg.DEFAULTBUTTON because you've already defined it as the controlsource. I'm not sure why you're adding 1 to that value anyway. Could that be where your problem is coming from? When I comment out that line and run your code, if I click any button in the command group and then click the "Refresh cycle" button, I see the correct value shown for the command group. Same thing with the option group.
