To determine if the cell that you just selected is in a defined range, follow these steps:

2. Select the range or ranges of cells that you want to name.
3. On the Insert menu, point to Name, and then click Define.
4. Type MyDefinedRange as the name for the range, and then click OK.
5. Press ALT+F11 to open the Visual Basic Editor, double-click your worksheet in the Project Explorer, and then type or paste the following code:

   Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
       
       If Not Intersect(Target, Range("MyDefinedRange")) Is Nothing Then
       
           MsgBox Target.Address & " is in MyDefinedRange."
   
           'include code here.
       Else
       
           MsgBox Target.Address & " is NOT in MyDefinedRange."
   
           'include code here.
       End If
   End Sub
   					

6. Quit the Visual Basic Editor and return to your worksheet.
7. Click anywhere in your worksheet. Note that you receive a message indicating whether you clicked in the specified range.
