using a ^ says "not one of these" and using [] says group these together
how about saying if you find something that is not a number or a letter:
<cfif REFindNoCase('^[A-Z0-9]', variable)>
ERROR
<cfelse>
do processing
</cfif>
what you said is:
find 0 or more alpha chars and 0 or more digits next to it
which works with any string on the planet!
I hope this helps!
