run macro based on combination of values from 2 dropdown lists

hi! i'm a new member of this forum and i would just like to ask for help in running an excel macro using vba (i'm also a beginner in vba).
I've read in one of the threads here how to run a macro from a dropdown list (data validation)
However, what if i have 2 dropdown lists? and i want to run a macro based on the combination of values in the
2 lists? How do I go about it? Help is very much appreciated. Thanks.

My base code was the vba code from Leith Ross below. How can I modify this to 2 dropdown lists?


Private Sub Worksheet_Change(ByVal Target As Range)

Dim Addx As String
Dim Rng As Range

Addx = Target.Validation.Formula1
Set Rng = Range(Right(Addx, Len(Addx) - 1))

If Target.Address = "$E$1" Then
Select Case Target.Value
Case Is = Rng.Cells(1, 1) 'First Drop Down Item
Call MacroA
Case Is = Rng.Cells(2, 1) 'Second Drop Down Item
Call MacroB
Case Is = Rng.Cells(3, 1) 'Third Drop Down Item
Call MacroC
End Select
End If

End Sub
