Curt, in both PlanMaker 2006 and Excel 2003 I get three worksheets labelled Ark1, Ark2, and Ark3. Only Ark1 contains anything and that is "50" in cell A:1. Is this what you posted? If so, what is the purpose? Loki, is this what you are getting as well, in openoffice.org? Spreadsheet should handle an Excel 2003 file no problem...
