CRAP!!  I can't tell you how many times I looked at that code and didn't 
see it!
    But, that's all it took was to spell the var correctly, of course. I 
am severely humbled and owe you a drink at the local bar were it 
possible, or some other thing you'd appreciate if you're not a drinker! 
  Any chance you live in far upstate NY?

Regards,
