First off, thanks for your patience.

Of course! How dim can I get?

No, in my clumsy kludgey way, I wanted to avoid possible collisions by
creating tables at random (I could always increase the seed range
enormously) while input is made, this is sent back to the user to verify
and, upon verification, the data is dumped into the table proper and the
rand-generated table dropped.

If you mean -
$Query = "CREATE TABLE $TableName ('
.. ' `id` SMALLINT(3) NOT NULL AUTO_INCREMENT, '
.. ' `firstname` VARCHAR(255) NOT NULL,'
.. ' PRIMARY KEY (`id`)'
.. ' )";

alas, that doesn't do it.
