Checkbox onclick uncheck other checkboxes
<p>I have 6 checkboxes, one for each business day and one that says 'all'.</p>

<p>What i want to be able to do is uncheck all the other boxes if someone clicks the 'all' checkbox if that makes sense.</p>

<p>For example, if someone has clicked monday and wednesday ... then they come in and click the 'all' checkbox, then the monday and wednesday checkbox should uncheck.</p>

<p>Cheers,</p>
