As usual, your assistance was not only very explicit but also extremely 
helpful. But this seems to be how you handle all your replies; you 
dispense a lot of good advice. I find myself in your debt. Again.

delve into it the more I realize needs to be done) I'll post it on the FPC 
site!  :-)

Thanks again.
