Please help, I have designed a simple spreadsheet that
uses Check Boxes and Option Buttons from the Control
Toolbox and I am trying to make a small VBA routine to
clear them all.
I thought I could use:

Sub Clear_cb_ob()
Dim cb As CheckBox
Dim ob As OptionButton
For Each cb In Sheet1
cb.Value = False
Next
For Each ob In Sheet1
ob.Clear
Next
End Sub

But I just get:
Object doesn't support this property or method
