Use structKeyExists. cfif structKeyExists(form, qty_#upd#) On Tue, Aug 20, 2013 at 10:48 AM, Rick Sanders r...@webenergy.ca wrote: Hey guys, I'm trying to add multiple items to a database based on if a check box is checked.

Re: Syntax is driving me nuts!
IsDefined does not accept array notation. You need to rewrite it using dot notation: IsDefined(form.rel_#ar#) or IsDefined(form.rel_ ar) The other option is to use StructKeyExists, which is generally preferred because it is a little more precise than isDefined: structKeyExists(form, rel_ ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:356504 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
RE: Syntax is driving me nuts!
Try structkeyexists cfif structKeyExists(Form, rel_ ar) If you really need to use isdefined, it would be: cfif isDefined(form.rel_ ar) Steve -Original Message- From: Rick Sanders [mailto:r...@webenergy.ca] Sent: Tuesday, August 20, 2013 11:49 AM To: cf-talk Subject: Syntax is driving me nuts!
