Try structkeyexists
<cfif structKeyExists(Form, "rel_" & ar)>
If you really need to use isdefined, it would be:
<cfif isDefined("form.rel_" & ar)>

Subject: Syntax is driving me nuts!
Hey guys,
I'm trying to add multiple items to a database based on if a check box is
checked.
This code works fine:
<cfif IsNumeric(#form['qty_' & upd]#)>
But I want to make sure the box is checked or not. When I do this:
<cfif IsDefined("#form['rel_' & ar]#")>
I get: Element rel_1 is undefined in a Java object of type class
coldfusion.filter.FormScope.
If I do this:
<cfif IsDefined("form['rel_' & ar]")>
I get: Parameter 1 of function IsDefined, which is now form['rel_' & ar], must
be a syntactically valid variable name.
I'm doing all this in a loop. The form's check boxes are defined as:
rel_#currentrow#. Then I'm looping around them:
<cfloop index="ar" from="1" to="#form.numrows#">
Numrows comes from the recordcount of the hidden form variable output query
displaying the checkboxes.
All I need to know is what the right syntax I need to use for IsDefined?
Kind Regards,
Rick Sanders
