Works in IE but not FF - Can't get image working

I am building a tab menu and I can get the image for the left hand tab to show up in IE but not FF. Any help would be greatly appreciated.

<style type="text/css">
p, h1, h2, h3, h4, h5, h6, ul, ol, fieldset, form {
      margin  : 0;
      padding : 0;
  }
  
/*- Global nav-------------------------- */

    #global-nav {
      float:left;
	  width:760px;
      background:#FFF;
      font-size:100%;
      line-height:normal;
      }
    #global-nav ul {
	margin:0;
	padding:10px 0px 0 10px;
	list-style:none;
      }
    #global-nav li {
      display:inline;
      margin:0;
      padding:0 0 0 0;
      }
    #global-nav a {
      float:left;
      background:url("tableftI.gif") no-repeat left top;
      margin:0;
      padding:0 0 0px 4px;
	  font:15px Arial, Helvetica, sans-serif;
	  font-weight:bold;
      text-decoration:none;
      }
    #global-nav a span {
      float:left;
      display:block;
      background:url("tabrightI.gif") no-repeat right top;
      padding:5px 15px 4px 6px;
      color:#012358;
      }
    /* Commented Backslash Hack hides rule from IE5-Mac \*/
    #global-nav a span {float:none;}
    /* End IE5-Mac hack */
    #global-nav a:hover span {
      color:#012358;
	  text-decoration:underline;
      }
    
	#global-nav a#activetab span { 
	  background-position:100% -27px;color: #FFF;  
	  }
	  

#global-nav a:link#activetab, #global-nav a:visited#activetab, { 
      background-position: 0% -27px; 
	  } 
</style>

<div id="global-nav">
  <ul>
    <li><a id="activetab" href="#" title="Link 1"><span>Home</span></a></li>
    <li><a id="activetab" href="#" title="Link 2"><span>Travel</span></a></li>
    <li><a href="#" title="Longer Link Text"><span>Insurance</span></a></li>
    <li><a href="#" title="Link 3"><span>Cars &amp; Car Care</span></a></li>
    <li><a href="#" title="Link 5"><span>Membership</span></a></li>
    <li><a href="#" title="Link 6"><span>Newsroom</span></a></li>
	<li><a href="#" title="Link 7"><span>Your Profile</span></a></li>
  </ul>
</div>

Code (markup):

 

try adding a 'display:block' to '#global-nav a'

 

Thanks for help. Turns out I have an extra ","

That was messing me up.
