Have you considdered using a Structure in stead of an array?
You can then i believe use StructKeyExists to test with a key has been
created

Subject: Arrays and CFIF
I have an array that catalogues a bunch of products and categories... for
instance, ProductIDArray[1][1] is "Case" and ProductIDArray[1][2] could be
"Mid Tower." With that in mind, this is for a system configurator... now,
there are checkboxes for SOftware... if they check one, then it goes into
the productIDArray... if they check two, then ProductIDArray[21][1] becomes
Additional Software and ProductIDArray[21][2] becomes two product ID's like
131,132. So... all I want to do is say "If ProductIDArray[21][2] has a
value, then do the following..."
How can I do that? The code I'm trying is:
<CFIF len(#ProductIDArray[21][2]#) IS NOT 0>
This comes back with the following error...
Error Diagnostic Information
The element at position 21 in dimension 1 of object "ProductIDArray" cannot
be found. The object has elements in positions 1 through 20. Please, modify
the index expression.
The error occurred while evaluating the expression:
len(#ProductIDArray[21][2]#) IS NOT 0
