I have a map of 195 precincts in a county. I want to add to the attribute table a spread sheet with 1 value per precinct. Is this a join? How can I get it to add to the attribute table? I tried the join data but the "ok" is never able to be clicked. Advise?
to be able to join one thing to the other they both need to have a field with a unique identifier, which the joint will be based on. Do you have such a field on both attribute tables?
