Help with CSS on proxy site

Hi. Can someone please help me with the CSS on my proxy site. The person who has made the template said that the problme I am having in IE (where the posts move down below the sidebar) is because something is wrong in the stylesheet because when i put in my getresponse code, it moves down. Without the getresponse code it's fine. The site is www.proxyfido.com It uses a darkmambo WP template found here http://themes.blogflux.com/theme/481.html

I have no idea how to use CSS (well,I know very little)

The getresponse code is this

<!-- GetResponse subscription form | start -->

<form action="http://www.getresponse.com/cgi-bin/add.cgi" method="post" id="GRSubscribeForm" accept-charset="UTF-8">
<fieldset>
<table>
<center> Sign up for our newsletter to recieve free proxy updates every sunday for fresh use monday through friday at school or work.

<tr>
<td>
<label for="GRCategory2">Name</label>:
</td>
<td><input type="text" name="category2" size="14" id="GRCategory2" /></td>
</tr><tr>
<td><label for="GRCategory3">E-Mail</label>:</td>
<td><input type="text" name="category3" size="14" id="GRCategory3" /></td>
</tr>

</table>
<input type="submit" value="Recieve Weekly Proxy Updates" />

<input type="hidden" name="category1" value="dailyproxy" /> 

<input type="hidden" name="ref" value="007" />
<input type="hidden" name="getpostdata" value="get" />
</form>
<style>
<!--
/* form box */
#GRSubscribeForm fieldset {
width: 260px; 
border: 0;
}
		
/* comment about GetResponse */
#GRSubscribeForm p {
font-size: x-small;
}
		
/* table used to position form elements */
#GRSubscribeForm table {
border: 0;
}
		
-->
</style>
<!-- GetResponse subscription form | end -->

Code (markup):

Someone please help, Im desperate.

I looked at your site and didn't find the GetResponse code there (neither visually, nor in the source code).

 

i am using another template. tHere is no getresponse code anymore.
