Hi Banaticus,

Looking at the code you posted, your IF statement looks backwards! Are you checking to see if MondayNoonBox contains a 1? If so the line should read as follows:

Private Sub SundayNoonBox_Click()
    If MondayNoonBox.Value = 1 Then
        TuesdayNoonBox.Value = 1
    Else
        TuesdayNoonBox.Value = 0
    End If
End Sub
If this doesn't solve your problem, I really need to see a sample of the workbook. Can you post a copy? Be careful about any sensitive data, and try to post a small version if the file is particularly large.

I hope this helps, please let me know!

Regards,

David
