Hi Dan,
Thanks for the reply. That mostly worked (see below), although I'm admittedly perplexed why changing the raster layer to a .tif file resolved the problem.
I say mostly, because the raster layer I'm sampling from has two fields: "ObjectID" and "Value", which both contain the same sequence of numbers up until 6598, at which point the "Value" field skips number 6598, while the ObjectID field does not. This wouldn't be a problem, except that the new sample data references the vegetation data with a field called "fveg15_1", which I assume is a sequence of numbers that ties back to either the ObjectID or Value field in the sampled raster layer. Since the raster attribute table has other information I need, I have to do a join, but now I'm not sure which field to join to. Any thoughts?
Thanks again for the help!
Doug
