I want to divide the counties into Districts and color each district a different color. The original data table contains the When you say "divide the counties" do you have the geographic boundaries of the districts is the second "table"? No, I don't have boundaries for the Districts, except as they include the individual counties. Divide was a bad choice of terms. I actually want to group the counties. That is Counties 1 - 15 are District A, Counties 16 - 30 are District B etc. Of course, they aren't numbered, they are named. information on each county, but does not contain the District information. I have a different table that contains the county name (identical to the original table) and the District designation (A, B, C etc) I can't find a way to import the second table into the project and sync it with the first, so I can then color District A red and District B green etc. Can you add just the districts and color them all different colors? That's what I'm trying to do. I could, for instance, add the district designations in a new column in the current DBF table, but my reading seems to indicate that this is not a good idea. Thanks for your response, CJon
