I am trying to setup an IF statement so Excel can auto fill state abbreviations that match with the Area Code. I am having some success, until I reach a certian point. I have tried variations of the "&" code. But this only works to a certian point. The code I have that does work (up to 67) is as follows :

=IF(C3=Legend!$C$3,"NJ",”&”IF(C3=Legend!$C$4,"DC", ”&”IF(C3=Legend!$C$5,"CT",”&”IF(C3=Legend!$C$6,"AL ",”&”IF(C3=Legend!$C$7,"WA",”&”IF(C3=Legend!$C$8," ME",”&”IF(C3=Legend!$C$9,"ID",”&”IF(C3=Legend!$C$1 0,"CA",”&”IF(C3=Legend!$C$11,"TX",”&”IF(C3=Legend! $C$12,"NY",”&”IF(C3=Legend!$C$13,"CA",”&”IF(C3=Leg end!$C$14,"TX",”&”IF(C3=Legend!$C$15,"PA",”&”IF(C3 =Legend!$C$16,"OH",”&”IF(C3=Legend!$C$17,"IL",”&”I F(C3=Legend!$C$18,"MN",”&”IF(C3=Legend!$C$19,"IN", ”&”IF(C3=Legend!$C$20,"IL",”&”IF(C3=Legend!$C$21," LA",”&”IF(C3=Legend!$C$22,"MS",”&”IF(C3=Legend!$C$ 23,"GA",”&”IF(C3=Legend!$C$24,"MI",”&”IF(C3=Legend !$C$25,"OH",”&”IF(C3=Legend!$C$26,"FL",”&”IF(C3=Le gend!$C$27,"MD",”&”IF(C3=Legend!$C$28,"MI",”&”IF(C 3=Legend!$C$29,"AL",”&”IF(C3=Legend!$C$30,"NC",”&” IF(C3=Legend!$C$31,"WA",”&”IF(C3=Legend!$C$32,"TX" ,”&”IF(C3=Legend!$C$33,"AL",”&”IF(C3=Legend!$C$34, "IN",”&”IF(C3=Legend!$C$35,"WI",”&”IF(C3=Legend!$C $36,"PA",”&”IF(C3=Legend!$C$37,"MI",”&”IF(C3=Legen d!$C$37,"MI",”&”IF(C3=Legend!$C$38,"KY",”&”IF(C3=L egend!$C$39,"VA",”&”IF(C3=Legend!$C$39,"TX", ”&”IF(C3=Legend!$H$3,"MD", ”&”IF(C3=Legend!$H$4,"DE", ”&”IF(C3=Legend!$H$5,"CO", ”&”IF(C3=Legend!$H$6,"WV", ”&”IF(C3=Legend!$H$7,"FL", ”&”IF(C3=Legend!$H$8,"WY", ”&”IF(C3=Legend!$H$9,"NE",”&” IF(C3=Legend!$H$10,"IL", ”&”IF(C3=Legend!$H$11,"CA", ”&”IF(C3=Legend!$H$12,"IL", ”&”IF(C3=Legend!$H$13,"MI", ”&”IF(C3=Legend!$H$14,"MO", ”&”IF(C3=Legend!$H$15,"NY", ”&”IF(C3=Legend!$H$16,"KS", ”&”IF(C3=Legend!$H$17,"IN", ”&”IF(C3=Legend!$H$18,"LA", ”&”IF(C3=Legend!$H$19,"IA", ”&”IF(C3=Legend!$H$20,"MN", ”&”IF(C3=Legend!$H$21,"FL", ”&”IF(C3=Legend!$H$22,"CA", ”&”IF(C3=Legend!$H$23,"TX", ”&”IF(C3=Legend!$H$24,"OH", ”&”IF(C3=Legend!$H$25,"IL", ”&”IF(C3=Legend!$H$26,"AL", ”&”IF(C3=Legend!$H$27,"NC", ”&”IF(C3=Legend!$H$28,"LA", ”&”IF(C3=Legend!$H$29,"MA", ”&”IF(C3=Legend!$H$30,"NY", ”&”IF(C3=Legend!$H$31,"MA", ”&”IF(C3=Legend!$H$32,"FL", ”&”IF(C3=Legend!$H$33,"WA", ”&”IF(C3=Legend!$H$34,"TX", ”&”IF(C3=Legend!$H$35,"UT", ”&”IF(C3=Legend!$H$36,"FL","N/A")))))))))))))))))))))))))))))))))))))))))))))))) )))))))))))))))))))))))
