First, thank you for looking at this and your help.
I'm trying to use the formula below to tell me if a cell value in I3 is
listed in either A6:A2260 OR B6:B2260
=IF(ISNUMBER(MATCH($I3,OR(('MSP Listing'!$A$6:$A$2260),('MSP
Listing'!$B$6:$B$2260)),0)),"Yes","No")
Can this be accomplished in this condensed formula or do I need to write a
multiple IF formula? The way it's written above I receive No but the part
does exist in A, it should say Yes.

Again, thank you for all your help
Joe
