a) You could do a Save As and save in Excel 97/2003 format
or
b) they could download the compatibility utility from
http://www.microsoft.com/downloads/d...displaylang=en

a) is better since it will stop you using new feature that will not carry
over to them
best wishes

Whenver I send an Excel 2007 attachment in an Email to others, they cannot
read or sometimes even open the attachment, because apparently it is not
compatible with older Windows Excel systems. This makes it impossible for
me
to send informartion in spreadsheet form to others who have need for it.
HELP!
