Duh, I feel silly ... long, extended brain fart. A few months ago I
looked at some code I think you wrote and saw you used Val() which
I've never used so looked it up ... I was thinking of it in the
context of using it to make sure something was a number before I used
it in a query ... so in my mind Val did nothing but 0 == false and
[anything else] == true. Is there a reason why evolt.org Val()
instead of IsNumeric() to do this validation?
