Hello everyone, I have two files - one fairly large (9000 records, 51 fields) and a second one with 500 records, and the same 51 fields. I can read and manipulate both files in Epidata Analysis but when I try to merge them using the common field of ID number, the second one has all missing variables, except the common field of ID number. I can't think what I'm doing wrong. Any guidance would be very helpful! Thanks, Susie Foster
