Can someone advise why this doesn't work; the userform (AskReClearData) shows
up okay, but when I check the 'CheckBoxClearCS' within the form (done in a
frame via the Control Toolbox) and then hit ok, the code essentially skips
the 5th line (re clear contents). If the checkbox is NOT selected and I hit
OK, then the code runs correctly.

Private Sub OKButton_Click()
Application.EnableEvents = True
If CheckBoxClearCS.Value = True Then
Worksheets("MMS for CS").Activate
Range("O3").ClearContents
Else
MsgBox ("Not checked")
Worksheets("MMS for CS").Activate
Range("A1").Select
End If
CheckBoxClearCS.Value = 0
AskReClearData.Hide
End Sub
