counting checked checkboxes using jquery (keeps returning 0)
<p>I would like to create an alert once too many check boxes have been checked.</p>

<p>Please see the setup here:</p>

<p>At the moment - the alert keep returning 0 - rather than counting the checkboxes...</p>

<p>Any suggestions would be great thanks!</p>
