wow sean! this is wild man!
Exactly what I needed to be learning! and you've set things out so logically
and helpfully!
thank you so much for this!
I'll go away and study it a bit, I'm slow at grasping these things eh,
and hopefully now I'll be able to do it. I'll let you know how I go with it
tomorrow.
Thanks again for all the great code examples and explanations!
Geoff c.
