Add-in Created; And Added Via Tools, Add-in

I've created and excel spreadsheet that has code like this in a Module named Print w/ in the workbook:
Sub Print_wsPrint()
Sheets("Print").PrintOut
End Sub

I have saved it as an MS Office Excel add-in.

I added the add-in to my excel environment via Tools, Add ins...and let it copy it to my C:Documents and SettingsjohnApplication DataMicrosoftAddIns directory.

But yet when I create a menu button and assign the Print_wsPrint to a custom menu, it complains and says "The macro Model.xls!Print_wsPrint cannot be found," where Model.xls is the workbook I am in. It's in my add-in, not in the current wb.
