Combo box in an array

I have two combo boxes in an array, named combo1(0) and combo1(1). How do I make different events when they are clicked?
The function is
private sub combo1_click(index as integer)

I need to have an array

VB Code:

Private Sub Combo1_Change(Index As Integer)
    If Index = 0 Then
        'combo1(0) clicked
    ElseIf Index = 1 Then
        'combo1(1) clicked
    End If
End Sub
