I'm hoping someone can assist me with a layout problem I'm having in IE8. The HTML for this is:

<!--[if IE]>
        <link rel="stylesheet" type="text/css" href="slider.css" />
<link rel="stylesheet" href="home/home.css" type="text/css" />
<script type="text/javascript" src=""></script>
<script type="text/javascript" src="contact/js/validation/validation.js"></script>
<body id="contact">
	<?php require_once('header_graphics.php'); ?>
		<div id="container">
				<?php require_once('logo_link.php'); ?>
    			<?php require_once('nav.php'); ?>
                <hr />
            <div id="contact_heading_container">
            <div id="contact_heading">
            <h2>Contact Me</h2>
            <hr />
                 <div class="contact_blurb_container">
            <p>If you would like to discuss some ideas for your new project, find out more information about me or if you would just like to say hi, I would love to hear from you! Please contact me using the form to the right or via one of the following methods listed below:<br /><br />
            <strong>Phone</strong> 604 582 7440<br />
            <strong>Cell</strong> 778 321 7441<br /><br />
            Download a print version of my resume below:<br /><br />
            <span class="underline"><a href="contact/images/CV_April_2010.pdf">Download Resume</a></span><span class="pdf_padding"><img src="contact/images/pdficon_small.gif" border="0" alt="pdf icon" title="pdf icon" /></span></p>

                  <div id="contact_form_container">
                        <form action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contact_form" name="contact_form" method="post">
    					<p class="contact_ptags"><label for="name">Name</label><br />
                        <input id="name" type="text" value="" name="name" size="30" /><br /><br /></p>
    					<p class="contact_ptags"><label for="email">Email</label><br />
                        <input id="email" type="text" value="" name="email" size="30"/><br /><br /><br /></p>
    					<p class="contact_ptags"><label for="message">Comments</label><br />
                        <textarea id="comments" rows="6" cols="40"  name="comments"></textarea><br /><br /></p>
    					<p class="contact_ptags"><input id="submit_button" type="submit" name="submit" value="" /></p>
						</form><br /><br />
                        <div id="thanks_container">
                        <?php if(isset($hasError)) { //If errors are found ?>
							<p class="error">Please check if you've filled all the fields with valid information. Thank you.</p>
						<?php } ?>

						<?php if(isset($emailSent) && $emailSent == true) { //If email is sent ?>
						<p><strong>Email Successfully Sent!</strong></p>
						<p>Thank you <strong><?php echo $name;?></strong> for using my contact form! Your email was successfully sent and I will be in touch with you soon.</p>
						<?php } ?>
        <?php include('footer.php'); ?>

and the css I'm having a problem with is:

.contact_ptags {
#submit_button {
	background:url(../contact/images/submit_button_static.png) no-repeat;
#submit_button:hover {
	background:url(../contact/images/submit_button_hover.png) no-repeat;

My problem is that setting margin-right:-10px causes a gap on the right side of the page in IE8 instead of moving my submit button over to position it the way I want. Does anyone know how I would effectively move my submit button to the right without creating a gap on the right side of the page in IE8?

Thank-you for any help!
