Don't know if this will help but you could 'walk' the structure and then decide   <cfset stParent = application.page> <cfset sFullkey = ""> <cfloop index="key" list="#url.page#" delimiters=".">    <cfif structKeyExists(stParent, key)>   <cfset stParent = stParent[key]>   <cfset sFullkey = listAppend(sFullkey, key, ".")>  <cfelse>   <cfbreak>  </cfif>   </cfloop>     but why not use isDefined() ??   Elliot   "Taco Fleur" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]... OK, here's the thing.   I know to use structKeyExists instead of isDefined, my problem with structKeyExists is that the structure reference is dynamic, i.e. application.page[ url.page ] so I could check if the key exists on the first level, i.e. it is structKeyExists(application.page["index"], "description") Now if we go another level down in the site it is   application.page[ url.page ] application.page["index.blog"]   If we would go down another level it would be application.page["index.blog.archive"] etc. as you can see it can not work with structKeyExists   At the moment I just catch the error with a cftry, but it's not the cleanest way of doing it I guess.   Another funny thing is happening, for example I have two references to a key within a cftry block, and they do not exist, i.e. application.page.index.blog.description If I do not have a cftry around each call it still generates an error. I have never seen that before, normally (As far as I can remember) it just catched any error within a cftry, whether that is one or two errors.   Taco Fleur Blog http://www.tacofleur.com/index/blog/ Methodology http://www.tacofleur.com/index/methodology/ 0421 851 786 Tell me and I will forget Show me and I will remember Teach me and I will learn   --- You are currently subscribed to cfaussie as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED] MXDU2004 + Macromedia DevCon AsiaPac + Sydney, Australia http://www.mxdu.com/ + 24-25 February, 2004
