With the help of the community here I was able to find code that helped me
link hundreds of radio buttons on multiple worksheets to cells with a macro.
I am running into a strange situation where sometimes the links are broken
and I have to run the macro again (why is that happening?).

To ease my mind I would like to change the code to the workbook activate
event and have it run each time I open the workbook. I would like to change
the code to run on multiple worksheets (now it just has active worksheet).
Can someone please help me with my code below, I am a beginner with VBA:

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

Also, if someone knows a way to add a message box that automatically opens
to says something like "workbook loading..." and then close when the macro
completes that would be great!!!

Thanks!
