Because I didn't write it until this morning, when I was asked to solve
the problem of multiple instances running simultaneously.  :-)

What record do you sit on?  How do you handle multiple people running the
report simultaneously?

It moves you to a unique record, thereby allowing more than one instance
of the report to run at the same time.
