FORM.FieldNames Checkboxes

Hey

Im trying to retreive the value of a checkbox in my script i.e. checked/unchecked.
Problem is if i uncheck the box on the form and submit it, the checkbox is not picked up in the form variables.
Any Ideas?

<td><input type="checkbox" name="CONTACTED" value="#getClientTransactions.paymentAttemptID#" <cfif getClientTransactions.Contacted eq 1>checked="true"</cfif> ></td>

thats how checkboxes work...if they are unchecked they are not sent as part of the form post...if u want the value irrespective of whether the checkbox is checked or not then use hidden fields

thats how checkboxes work...then use hidden fields
A simplier approach is to use the CFPARAM tag:

<cfparam name="FORM.Contacted" default="unchecked">

You can also check to see if is defined in the page that parses it.

e.g.

<cfif IsDefined(FORM.checkbox)>
...
<cfelse>
...
</cfif>
