Drive scenarios with a combo box

Hi guys,

I got a combo box (name: ComboBox1 ) with 3 options : A,B,C

Each option has it own scenario.

In the sheet code I got:

Private Sub ComboBox1_Change()
   ActiveSheet.Scenarios(ComboBox1.Value).Show
End Sub

Everything works, but I still have the same error that show up everytime:
Error 1004 : Show method of scenario class failed
