That's a perfectly valid point.  And as I said, I'd be able to get the proper
record number for 99+%.  Happily, there aren't situations like the one you
describe.  The names of the cards are almost all distinguishable within the
first 9 characters. That's why I chose it as my aribitrary value. :p

Already done in temporary holding tables.

Done.  These are the tables I'm trying to move the data to.

Haven't done this.  Perhaps it would be a good idea to update the temp table with
the proper values before moving over the the actual table.  This would certainly
make things a heck of a lot easier!

Thank you very much for your help and your advice!
