When I save work on my pc to print off on the main one, I click on Save as and then it should come up as type of doc EG. word doc and then year (1997 - 2003), if that makes sense.
Yeah, When you are saving it. Go to 'Save as' - then choose 97-2003 workbook. 2007 saves files at xlsx I believe - it needs to be xls.
Did you consider downloading OpenOffice? It would be a much better bet than trying to use Office 97 (and it's free). Compatible with all vedrsions of Office.... http://www.openoffice.org/
