Whenever I try to copy a worksheet in a particular Excel 2007 file (.xlsm), I get the following message:

A formula or sheet you want to move or copy contains the name ‘ACwvu.prime._.view.’, which already exists on the destination worksheet. Do you want to use this version of the name?
• To use the name as defined in the destination sheet, click Yes.
• To rename the range referred to in the formula or worksheet, click No, and enter a new name in the Name Conflict dialog box.

I can't find the name in the name manager or in the visual basic module. I would appreciate any help with this error.

Thanks,

Don
