how can i make this code work as a toggle?

i found this post here

now how can i make this a toggle?

Private Sub Worksheet_Deactivate()
 ThisWorkbook.Sheets(Array("Sheet3", "Sheet4", "Sheet5", "Sheet6")).Visible = False
End Sub

so start with an if statement:

Private Sub Worksheet_Toggle()
if sheet3.visible = True then
 ThisWorkbook.Sheets(Array("Sheet3", "Sheet4", "Sheet5", "Sheet6")).Visible = False
else
 ThisWorkbook.Sheets(Array("Sheet3", "Sheet4", "Sheet5", "Sheet6")).Visible = True

not sure of the terminology on the IF statement, but once that is figured out, it should work, right?

thanks for your help.
