RE: isDefined() finesse
Because the isdefined function doesn't care what the value of the variable you are passing you don't need to use the evaluate function. However if you wanted to output that value you would have to use something like: cfoutput#Evaluate(form.serNum#i#)#/cfoutput -Original Message- From: j cc [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 26, 2002 9:12 AM To: CF-Talk Subject: isDefined() finesse cfif isDefined(Form.SerNum#i#) at first I thought it would be isDefined(evaluate(form.serNum#i#)) BUT what you had worked fine when i put it in CF 5. for a test I did this... form name=foo action=test.cfm method=post input type=hidden name=serNum1 value=foo input type=submit value=go /form cfset i =1 cfif isDefined(form.serNum#i#) foo! /cfif and after submitting the form, I received foo! as my output. -jc ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribeforumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Structure your ColdFusion code with Fusebox.

RE: -isDefined() finesse
Well your original code should have worked as well. Also note you could do: isDefined(form.sernum i) as well as structKeyExists(form,sernum#i#) === Raymond Camden, ColdFusion Jedi Master for Hire Email: [EMAIL PROTECTED] WWW : www.camdenfamily.com/morpheus Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda -Original Message- From: Brian Scandale [mailto:[EMAIL PROTECTED]] Sent: Monday, November 25, 2002 3:18 PM To: CF-Talk Subject: Re: -isDefined() finesse Sorry, just worked it out... -cfif isDefined(Form.SerNum#i#) At 01:11 PM 11/25/02, you wrote: I am trying to see if a particular dynamic variable is defined... but having trouble building the ifDefined argument.

RE: -isDefined() finesse
Another Option: -cfloop index=i from=1 to=#theSerNums.RecordCount# -cfif structKeyExists(Form,'SerNum' i) DoSomething -cfelse DoSomethingElse -/cfif -/cfloop however what you have looks fine to me.
