Hi,
I'm making a membership spreadsheet for my club using Excel 2010.
This finished Spreadsheet will be handed to our secretary who uses an
earlier version of Excel.
I have conditional formatting in place and works fine.

Saving the spreadsheet as a 2003/2007 Spreadsheet gives a warning that the
conditional formatting
will be removed as it's not compatible with earlier versions.
I'm prepared to do it over so it can be used with the conditional formatting
in the earlier version.

Can I switch my 2010 version of excel to the compatibility of earlier
versions.

TIA.
