Option_Button.xlsx

Hello,

Please see the attached spreadsheet. There are 4 groups of option buttons. But the selection is not happening within the groups. I am able to select both option in "Group Box 20" . Group Box 21 and 23 is reflecting as Same group ( selecting one option in group box 21 removes option selected in group box 23) although both are separate. can someone help out on this please.

Thanks.
