If(vlookup statement
 

I have three columns that I need to return a vlookup value.

A B C
8 2 PSS

I want to lookup column A in my table to return the name, if not then lookup
B and return the name, if not then lookup C, otherwise give me "Part 1 -
Other". In this case none of A, B, or C is found so my result should be "Part
1 - Other". My lookup table is below:
