Problem with AJAX subscription form and custom fields

I use the AJAX subscription form http://www.campaignmonitor.com/downloads/ajax-subscription-form/ and it works so far with "Name" and "Email".
If I add a few custom fields, the form still works, but the custom information (Interests) won't show up in the subscriber database. Just the name and email address.
Any ideas?

<div id="theForm">

<form action="XXXXXXXXXXXXXX.com/t/y/s/djkuv/" method="post" id="subForm">
<div>
<label for="name">Name:</label><br /><input type="text" name="cm-name" id="name" /><br />
<label for="djkuv-djkuv">Email:</label><br /><input type="text" name="cm-djkuv-djkuv" id="djkuv-djkuv" /><br />
<label for="Interests">Interests:</label><br />
<input type="checkbox" name="cm-fo-jtiuul" id="cm75875" value="75875" /> <label for="cm75875">Hockey</label><br />
<input type="checkbox" name="cm-fo-jtiuul" id="cm75876" value="75876" /> <label for="cm75876">Soccer</label><br />
<input type="checkbox" name="cm-fo-jtiuul" id="cm75877" value="75877" /> <label for="cm75877">Baseball</label><br />

<input type="submit" value="Subscribe" />
</div>
</form>

</div>
<div id="confirmation" style="display: none;">Thanks for subscribing</div>
