HTML - Breaks Between Form Items.

I'm having trouble adding a line break between my form items. I've tried all the obvious solutions and nothing is working; either the breaks appear about the forms and below the text, or the form itself is moved to halfway across the page.
I've tried using <br> tags and I've tried
<tr>
<td colspan="2">
<br>
</td>
<tr>
and many variations, but none do what I what.

Here's my code:

Page Content goes here.
<BR><BR><BR>
<form id="form1" name="form1" method="post" action="http://www.usa-7.com/scripts/shared/refmlr">
<input name="destEmail" value="emailaddressgoeshere" type="hidden"/>
<input name="reqType" value="Contact Us" type="hidden" />
<input name="numReqParms" value="5" type="hidden" />

<script src="validate.js"></script>
<style>
input.invalid {background: #ff0000;}
input.valid [background: #afa; }
</style>

<table height="200" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td> First Name:&nbsp;</td>
<td><input name="First Name" size="30" maxlength="55" type="text" /></td>
</tr>
<tr>
<td> Last Name:&nbsp;</td>
<td><input name="Last Name" size="30" maxlength="55" type="text" /></td>
</tr>
<tr>
<td> Email Address:&nbsp;</td>
<td><input name="Email" size="30" maxlength="200" type="text" /></td>
</tr>
<tr>
<td> Phone Number:&nbsp;</td>
<td><input name="Phone" size="30" maxlength="35" type="text" /></td>
</tr>
<tr>
<td> Comments:&nbsp;</td>
<td><textarea name="Comments" cols="50" rows="8"></textarea></td>
</tr>
</tbody>
</table>


any help would be great.

Thanks!
