General ArcGIS novice and basically use if for thematic mapping of Census and other demographic data. I'm a demographer and former State Demographer of New York State. Still do some demographic consulting through my company RLS Demographics.
I've done numerous straight joins for Excel data to layers with now difficulty. Latest effort was a couple of months ago joining a spreadsheet with 50+ Census variables to a state layer for the entire U.S. Worked fine as it always used to. Today I'm doing a similar join with only a dozen variables for all NYS minor civil divisions. Repeatedly get this error. Any suggestions on why I'm getting it all of a sudden and how to fix it?
