With the help of Trevor Williams on this board I was able to easily link
hundred of group boxes (with 4 radio buttons in each) to the cell that they
were on top of. Here is the code:

Sub LinkOptBtns()
Dim GrpBox As GroupBox
Dim OptBtn As OptionButton
For Each OptBtn In ActiveSheet.OptionButtons
With OptBtn
.LinkedCell = .GroupBox.TopLeftCell.Address
End With
Next
End Sub


My problem is that I am starting to lose the links and I am finding myself
running the code randomly to re-link them. Can someone help me make the
control links permanent? I want to distribute my workbook to many users and
will not allow them to access to the VBA.

Thanks.
