Thanks Mark...

"quite easily write yourself a quick binary search algorithm"

you make me chuckle... *chuckle*  I'll get to that right after I whip
up my CFC for splitting atoms.

I'll have a look at the java thing.

Are array's overly bursonsome?  I am putting all my form field
attributes (name, type, etc) in an array, which will likely end up
being 3-dimensions.  The information in the array is coming from 3 or
4 queries, so either I loop through the queries in the body of the
page (I think kinda messy) or loop through my single array.  I am not
adding any looping to create the array.

Cheers,

Chad
