Hi Dave,

Thank you, you are, of course correct.

What moving the On Error Goto 0 into the loop does do is to clear the error
at each pass and, thus, enable code to be run in response to any error.

Your code worked for me.

In the VBE, try:
Tools|Options|General tab
Change the error trapping setting to "break on unhandled errors"

If I had "break on all errors" set, then I got an error.

What causes On Error Resume Next to be ignored ??

I have a piece of code that exploits the Collection limit of unique key
values only, however it still throws an error when trying to add a
duplicate
key to the Collection - as if the On Error Resume Next is being ignored

Dim NoDupes As New Collection
Dim AllCells As Range, Cell As Range
Set AllCells = Range("A1:A100")

' The next statement ignores the error caused by attempting to add a
duplicate key to the collection.
On Error Resume Next
For Each Cell In AllCells
NoDupes.Add Cell.Value, CStr(Cell.Value)
Next Cell
' Resume normal error handling
On Error GoTo 0
