I am having some problems with my webpage displaying properly in firefox, In IE the page displays fine, but in Mozilla there is a big gap between the text above the form (For faster service, please....etc) and the form itself, I cannot workout why!?

HTML: 

<h2 class="title_main_contact">Feed Me</h2>
	<ul id="addressarea">
		<li><h3><img src="Images/contact_bn.gif"  /></h3></li>

		<li class="contact_space"><span class="txt_pink">Business</span></li>
		<li>22 Whimple Street</li>
		<li>Plymouth</li>
		<li>Devon</li>

		<li class="contact_space"><img src="Images/icon_phone.gif" alt="Telephone" /><span class="txt_pink">01752 666666</span></li>
		<li><img src="Images/icon_fax.gif" alt="Fax" /><span class="txt_pink">01752 666666</span></li>

	</ul>

It sounds like your site is rendered in quirksmode. What document type are you using? What does your page look like in IE7? IE6? IE8? Safari? Opera?
