=IF(H26="","",IF(ISNA(MATCH(H26,ServerCodes,0)),"D","S"))

I am using this formula to to cause a cell to tell me if the data in the "H" column equals the codes listed in the Named list 'ServerCodes' . D=Desktop Computer S=Server

This has worked ok for me thus far, but have been thrown another bone by corporate headquarters. I must now reference two more Name lists to be labeled as CA. As you can see, my formula is an if statement, and Im not sure if more options can be added. So now I have the 3 Names lists, ServerCodes, RTScodes, and NBcodes. Can anyone provide input? I hope I provied enough info..... Basically, I need the column with code above, to differenciate, D, S, CA.
The CA would equal NBcodes and RTScodes.....
