Ok, after playing around with the code a bit, I figured it out. I needed to use NwSheet.OptionButton1.Value = True, instead of OptionButton1.Value = True. I couldn't explain why, but it does the trick. I am guessing it has something to do with it trying to change the option button status on all the buttons. Now, I am trying to figure out how to lock the previous option buttons so they can't be changed after the command button is clicked.
Sometimes I just need to talk through the process with someone/somewhere to figure it out. I appreciate the outlet for my mental excercises.
