That did it! I changed the suffix and everything worked as hoped. My one last question is whether there is a way to get rid of the yellow highlighting? I added my original table to the table with the boundary info, so now most of the columns are highlighted because they refer back to the original table (which is now hidden). I do see that one of our other DataExplorer tables has just the boundary data column high lighted. Would I need to merge them in the opposite direction if I wanted to minimize the yellow highlighting (just the boundary data). If I merged going in the opposite direction (to minimize the yellow highlighting), would that increase my chance of having issues with the mapping feature?
