I'm trying to merge 3 shapefiles.  They all have identical fields, came from the same source, they're just for different counties in my watershed.

I'm trying to combine them, and getting errors when using merge.
ERROR 000278: Failed on input OID 0, could not write value ' ' to output field NFADate

Any ideas what I'm doing wrong?
