Hello,
I'm working on an excel sheet and comparing multiple columns to determine if a
site to be eligible or not eligible for the program, the site can only have Failed one shop period or less. If the site Failed 2 times or more, they are not eligible. So based on the 3 shop periods shown, i'm trying to place either an 'eligible' or 'not eligible' in the empty column to the right.

SVB 2009 S1 2009 S2 2009 S3 Eligibel or Not Eligible
