is there anyway that i can execuate a macro whenever the user change the
selection in the drop down instead of the user need to select then click on a
button to execute

Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "H10" '<=== change to suit

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
'do your stuff
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.
