I've got a purchase order (pre Excel 2002) which was designed to assign an
automatic number everytime the template was opened and for ages I have tried
to get it to work again now we are using Excel 2003, but when I try to run
the macro I get a message that reads

"The numbering add-in must be loaded for optimal numbering and toolbar
behaviour. Please load this add-in into your Library directory".

The problem is I can fine this add-in anywhere... Can anyone help PLEASE!!!
It's driving me insane.
