Conditional format based on 3 way lookup

Hi All,

I'm having trouble coming up with a way to setup a table to do a lookup based on 3 values and then format 1 cell. I'm thinking it just the way the table is setup that needs to change but I can't seem to come up with a way to set it up. Please take a look at the attached and give me some suggestion. Hopefully the sheet/table is self explanatory. Thanks in advance!
