I am trying to look up UPC values in column B. If a UPC listed in Column B
is also listed anywhere in Column C, then I want to return 'Yes" in column D.
If not I want to return 'no". I am sure this is simple, but I can't figure
it out from Lookup help. Thanks!

example:

Column B Colum C Column D
77777 11111 YES
22222 77777 NO
55555 66666 NO
