The problem is the way you are using the Find function. You can't just use find inside a variable to do what you want. It needs to be used inside a statement. This should work:
<CFLOOP from="1" to="#ArrayLen(Mysection)#" index="APos"> <CFIF FindNoCase(SectionTitle[APos], VarTitle) IS TRUE> <CFSET Mysection=VarTitle> <CFELSE> <CFSET Mysection="ERROR"> </CFIF> </CFLOOP>

It works!
It works perfectly mate! Thanks a lot!!
I'll know that next time, do you always have to keep your script within CF tags in Cold Fusion or is there an alternative? Cheers

You CAN use the functions in a variable like this:
<cfoutput> #find( somewords, somemorewords )# </cfoutput> But all that does is return 0 or return the start position of the match, so it's probably not very useful to output that, but rather to use it in some other statement like a conditional. You can also you CFSCRIPT for some of this sort of thing. HTH
