Also, I would suggest finding the exact ColumnNum as part of the
handler- either from the header row, or a separate header variable.
If you don't, as the database evolves and columns are added (or
deleted), then you'll have to go back and change all your hardwired
column references... or change your data around to make the columns
right, both big hassles...
