Morning all,

Right then. I'm having trouble working this one out:

Cells A3:A500 contain product numbers, e.g. 1001, 1002, 1003 etc.. etc...
Cells G2:N2 are column headers, e.g. North2011, South2011, North2012, South2012 etc... etc...
Cell F2 is a lookup that will return a year, e.g. 2011, 2012, 2013 etc... etc...

Against each product is a "yes" if it was sold in the north or south region for each year. This could be both north and south, one or the other or none at all.

What I would like is a formula in cells E3:E500 that looks at the year in cell F2 and if there is a "yes" in either the North or South for that year to return "yes" otherwise blank.

Apologies for the long description but I am unable to upload a sample document due to firewalls.

Thanks for any help in advance!
