Hello Excel users and experts,

Win XP, Excel 2002

A number is scanned into cell A1 and the below code is called through a
change event macro. It finds that value in range aList and a date stamp is
entered 2 columns to the right of the find value. This works fine.

However, if there is NOT a value found in aList, then for some reason the
date stamp is entered in first row of aList, 2 columns over. What would be
the code to prompt a message box "Not Valid No." when there is no find? I
can't figure out how to "catch" the fact that a number was not found.

Sub BookReturnDate()

Dim aList As Range
Dim Bcode As Variant
Bcode = Range("A1").Value
If Bcode = "" Then Exit Sub

Set aList = Range("G2:G2505")
On Error Resume Next

aList.Select
Selection.Find(What:=Bcode).Activate
ActiveCell.Offset(0, 2).Value = Now

'If no find then msgbox "Goof Up"

End Sub

Thanks for your help,
Regards,
Howard
