Hi, I am trying to basically set up a sheet that will cross reference a set of species in an area to a preset list of species at risk. In my column a I have species listed form A2:A13 that are endangered, A14:A23 that are Threatened and A24:A40 that are special concern. I am trying to make my third column (C) reference any species that I list in the second column and say its appropriate designation. I have written this nested if/then statement however I keep getting the "You've Entered Too Many Arguments for this Function" notice. I am assuming I have a parentheses in the wrong place but I am not seeing my problem. If anyone can help or there is an easier formula for this then please let me know!

Current formula:

=IF(ISNA(MATCH(B2,A2:A13,0)),"N","Endangered",IF(ISNA(MATCH(B2,A14:A23,0)),"N","Threatened",IF(ISNA(MATCH(B2,A24:A40,0)),"N","Special Concern")))
