Do tables affect Contact Form 7?

I’m using the plugin Contact Form 7, and for some reason whenever I click “submit,” I get an error message that says the form can’t be sent. I’ve sent emails to the address the form is directed to go to, so I don’t think it’s a server issue. I’ve heard WordPress doesn’t always play nice with tables – do you think that could affect the form?

Here’s the website:

And here’s the code I’m using for the plugin:

<table width="600" border="0" cellspacing="5" cellpadding="0">
<tr><td width="30%">Name:</td>
<td width="70%">[text* contact-name class:form]</td></tr>
<tr><td>Email:</td>
<td>[email* email class:form]</td></tr>
<tr><td>Phone:</td>
<td>[text area 4/3 class:form "859"]-[text phone1 4/3 class:form]-[text phone2 5/4 class:form]</td></tr>
<tr><td>I'm interested in:</td>
<td>[select photo-type include_blank "Engagements" "Wedding Photography" "Portraits" "Maternity Session" "Newborn Session" "Pet Photography"]</td></tr>
<tr><td valign="top">Anything else?</td>
<td>[textarea any-else class:form]</textarea></td>
</tr>
</table>

<p>[submit "Send"]</p>
