Determine If Worksheet CommandButton Fired Event Code

When I click on a commandbutton20 on sheet1 it moves the user from sheet1 to sheet2, hides some columns & formats the height of a row in a range of cells I will refer to as Area X. On sheet 2 I have a target condition that if the user clicks on any part of Area X it move the cursor to cell C8. What I want to accomplish is that if commandbutton20 in clicked, the target condition is suspended. otherwise the target condition works. The code I wrote is as follows. What happens when I press F5 to execute it... a macro window pops up.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("a1:x3,e4:x6")) Is Nothing Then
If Worksheets(1).CommandButton20_Click() = True Then
Exit Sub
Else: Range("c8").Select
End If
End If
End Sub
