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

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!
