ISdefined for the checkbox

I have a form with 12 check boxes name sel1……sel12. I like to insert the once checked into a table. I’m using the following method to check for the boxes being defined.

<cfloop index="i" from="1" to="12">
<cfif isdefined(#form["sel" & i]#)>
Insert into table code here….
</cfif>
</cfloop>

In this case I have checked boxes with the name of sel1 and sel2, but not sel3 and that’s when I get this message.

Element sel3 is undefined in a Java object of type class coldfusion.filter.FormScope.

Thanks in advacne!

    You don't use octothorps with isDefined. You might find it easier to give all your checkboxes the same name and different values. Then You just need
    <cfif isDefined("form.sel")>
    <cfloop list = "#form.sel#">
    code
