I would like to use the SUMIF function to add up cells containing common
words, but not necessarily the same word, i.e.

Cell1 contains party123 value 100
Cell2 contains party 456 value 50
Cell3 contains poser 122 value 100
Cell4 conatins partypooper value 100

Therefore total cells containing "party" = cell 1+cell 2 +cell 4 = 250

Is it possible to do this?
