I have the following data:

A B C D
1/14/2013 1/1/2002 barg
1/14/2013 6/1/2012 nonbarg

and need to put a result into D as a result of the following factors:
If B is less A-5yrs and 'barg' is in C, then NA, otherwise Review and if C has 'nonbarg' always enter NA

I used * =IF(C5="barg",(IF(A5-(365*5)<B5,"NA", "Review"))) - and this works

However when I add the another clause I get the #VALUE error:
=IF(C6="nonbarg","NA","Done")+(IF(C6="barg",IF(A6-(365*5)<B6,"NA","Done")))

What an I doing wrong? Can someone help put me out of my misery? Many thanks for your attention.
