Making Command Button invisible from within the click-event

I am having problems in making a command button invisible (worksheet, not form) after it has been clicked (Excel 2007). I tried this :

Private Sub ShowAsGraph_Click()
    
    'This is what the button should, and does, do.
    ActiveSheet.ChartObjects("Dashboard_Chart").Visible = True
    
    'Now I want to hide the button to ensure it does'nt get re-clicked
    ActiveSheet.Shapes("ShowAsGraph").Visible = False
    '.... but it stays visible.


End Sub

without effect. I imagine the click-event is refusing to hide its own object because it is still executing.

Thanks aisietie, that did the trick. (Still can't see why refering to it as its shape-object doesn't work and the direct reference does. Who cares!)
