Wow Michael, that' s pretty amazing of you. Thanks!

For this particular case, I don't really care about the second 
dimension.  I simply wanted to be able to get one of each from an already 
existing array.  It's a matter of top lining for a report. The first 
dimension is actually a client number, and the second dimension is a 
variety of contact details (phone, email, ect...) The purpose in the case 
was to say "client (array[1]) paid up today".

Quick question: is the ability to use myFunction()  available in 4.5's 
version of cfscript? If so, I've just learned something that'll change a 
lot for me. If it's not, this will be a most excellent guide for converting 
to tags.

Incidentally, I was looking at some code on cflib.org to guide me, 
ArrayFind is at <http://www.cflib.org/udf.cfm?ID=715>

Thanks Michael that's incredibly helpful, I was busting my skull on it.
