Hi,

I just upgraded from Excel 2003 to Excel 2007. When I saved an Excel
document written with Excel 2003, I got the following Compatibility Checker
message: "The following features in this workbook are not supported by
earlier versions of Excel...To keepo all of your features, click Cancel, and
then save the file in one of the new file formats."

Question: What new file format do I use and how do I change the current file
format to the new one?

Thank you.
