I have two radio buttons created on Sheet1 of a 3-sheet workbook. I
have named the buttons opMemo and opNoMemo in the Properties of each.
When clicked, the buttons change the text of several cells on Sheet1
via _Click events. My problem is this: I want the opNoM button to be
checked when the workbook is opened.

I have this code under ThisWorkbook:

Private Sub Workbook_open()
Call opNoM
End Sub

The procedure opNoM is in a Module in the Project and looks like this:

Public Sub opNoM()
.... change the text in various cells on Sheet1
End Sub

This successfully sets up the sheet for the NoMemo mode, but if the
opMemo button was checked the last time the workbook was saved, it is
still checked when the workbook is opened. How do I ensure that the
opNoMemo button is checked when the workbook is opened?

Any help is greatly appreciated.
