Thank you I will try this out. I am also trying to display the percent different in permiums on a lat/long level across california. I have a seperate sheet in my excel table that has OBJECTID (numbered 1-72,425), LAT, LONG and the PCTDIFFPREM. When I go to display xy data it is not projecting correctly over the state of california layer. X field: long, Y field: lat. I get the below message even though I have an objectID column in my table. How do I fix this?
