Not quite sure what you mean but as a guess

If you want a different macro to run depending on what a cell contains then...
'In the SHEETS code module...
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Target.Row = 1 And Target.Column = 1 Then
Select Case Target.Value
Case 1
Call Macro1()
Case 3
Call Macro2()
Case 3
Call Macro3()
Else
'Do nothing
End Select
End If
End Sub



If you need a certain macro to run only when a cell = a certain value then...
'In the SHEETS code module...
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Target.Row = 1 And Target.Column = 1 Then
Select Case Target.Value
Case 1, 2, 3
TheRealMacro Target 'Call the real macro
End Select
End If
End Sub

Private Sub TheRealMacro(Target As Excel.Range)
MsgBox "Macro running: You typed " & Target.Value
End Sub
