Excel2003 ... I have no knowledge on "Names" I have not used them.

I am trying to copy/paste a small range of cells from a Worksheet in one
Workbook to a WS in another WB. Issue is the following error message:

"A formula or sheet you want to move or copy contains the name 'Now', which
already exist on the Destination Worksheet." ... The remainder of the message
simply gives me options.)

How do I find the 'Now' Name in the Destination Worksheet? Thanks ... Kha
