Nancy, I took a quick look at your training set data file and I see a couple of problems. 1. You have some name fields that aren't legal names in the header. 2. It appears that you have more variable names in your header than you have data fields on each line. These issues will need to be cleaned up before you can read the file. Dan Daniel J.
