I need to have COL_C say yes if any value in COL_B = any value in COL_A.
I tried the following: =if($A$2:$A$5=B2, "yes", "no") . . . didn't work. :(
I read the formula as "if range a2 to a5 = B2, then say yes. . .

Any ideas?

Try...

C2, copied down:

=IF(ISNUMBER(MATCH(B2,$A$2:$A$5,0)),"Yes","No")

Hope this helps!
