Header not playing OK in IE8, HELP!

[Mymmeli]

Hi,

I have this code for the header and it plays fine in Firefox, but not in IE8. Why is that and how to fix the problem. I am ready to launch my site, but this latest bugger keeps me from launching... Can you help?


<div id="header"> <div class="headerleft"> <a href=http://myllyme.com>" /></a> </div> <div class="headerright"> <form id="searchformheader" method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <input type="text" value="Search this website..." name="s" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> <input type="submit" id="searchbutton" value="GO" /></form> </div></div>
