Form check box component

I have been searching for ages now and need a solution to a MX 2004 components problem in conjunction with coldfusion.

I have made quite a simple email form that works and outputs with the aid of a cfm file quite sweetly. As soon as you introuduce a checkbox component, the email does not come through. My question is then, how do you get the variables from the checkboxes sent to the cfm form?

here is link to download the form:

www.cynergyhealthcare.com/form

her is the cfm code:

<cfmail to="paul@cynergymedical.com" from="#form.fullname#<#form.email#>" subject=“Healthcare User Response” server=“mail.das.uk.net” type=“HTML”>

<B>Name:</B> #form.fullname#<br><br>
<B>Email:</B> #form.email#<br><br>
<B>Message</B> #form.message#
<B>i like crisps</B> #form.yesCrisps# #form.noCrisps#

</cfmail>


Any help much appreciated.
