Hi
one idea: If you have your drop-down box (created by 'Data -
Validaion') in cell A1 put the following code in your worksheet module:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Intersect(Target, Me.Range("A1")) Is Nothing Then Exit Sub
On Error GoTo CleanUp:
With Target
Application.EnableEvents = False
select case .value
case "constellation1"
'code for constellation 1
case "constellation2"
'code for constellation 2
'.....
end select
End With
CleanUp:
Application.EnableEvents = True
End Sub
You may change this to your needs as I do not know which kind of code
