I get an error message when trying to open up a spreadsheet in excel 2000. The error reads AN ERROR OCCURED WHILE LOADING 'SHEET 91111111111111121'. DO YOU WANT TO CONTINUE LOADING THE PROJECT? The spreadsheet opens fine in Excel 97. It has macros, but even when disabling macros, i get the error. It looks like this is the only sheet that has the problem. Any ideas?
