I am running Excel 2002. I have a Workbook with 4 worksheets. I created a
Control Option Button (OptBtn01) on Sheet1. I have a Control Check Box
(ChkBx01) on Sheet4. I would like to change Control Check Box (ChkBx01) to
disabled (Enabled = False) whenever the Control Option Button (OptBtn01)
Value is True. Can anyone help?

Thanks in advance.
