Thanks Tuviah for the information. What you wrote looks like Greek at a
glance. But the steps will help a lot. I just need to work it out and buy
a copy of your external as I will need it. I have downloaded your demo and
will mess with it there for the next few days.
But, I may bring this thread back to life if needed. :)
Thanks again for taking the time to write this out.
