Hi,
New member Mike Basingstoke here.
Got a problem since I upgraded (yesterday) to Office 2010 whereby a customer who uses Excel2003 who could share my files created in Excel 2007 now gets #NAME? errors. The functions that seem to be triggering this are nothing esoteric - just tame stuff like IFERROR and INDEX and MATCH. I've researched this in help and on Google extensively but I cannot find a fix. Can anyone help? Much obliged. Mike
