I can't figure out why a vlookup formula will not work. I'm getting #N/A errors. I've used vlookup numerous times but never had this big of a challenge. It's almost like a data type problem. In the table_array, I have alpha-numeric data in column 1 and numeric data in column 2. I've changed the cell format in the table_array several times but can't get it to work. Does this sound familiar to anyone? Thanks.
