I'm having an awful time with an extra new line in my navigation bar. I want to have three links on the left then two on the right. But, I can't stop the links on the right from going down a line. Here is what i have:

HTML Code:

	padding: 0;
	border: 0;
	outline: 0;
	font-size: 100%;
	vertical-align: baseline;

}

div#header
{
   background-color:     #0000FF;
   padding:             20px 20px 20px 20px;
   width:               600px;
}
ul#topNav li
{
   list-style-type: none;
   display:         inline;
}
ul#topNav li a
{
   color:           #FFFFFF;
   display:         inline;
   border-style:    solid;
   border-width:    1px;
   padding:         10px 10px 10px 10px;
}
ul#topButtonBar li
{
   list-style-type: none;
   float:           left;
   display:         inline;
}
ul#topButtonBar li a
{
   color:           #000000;
   border-style:    solid;
   border-width:    1px;

   border-style:    solid;
   border-width:    1px;
   border-color:    #FF0000;
   padding:         0px;
   float:           right;
   display:         inline;
}

</style>
</head>
<body>

<div id="header">
  <ul id="topNav" class="nav">
     <li><a href="#">Link 1</a></li>
     <li><a href="#">Link 2</a></li>
     <li><a href="#">Link 3</a></li>
  </ul>
  <div class="floatRight">
    <ul id="topButtonBar">
       <li><a href="#">Right Link 1</a></li>
       <li><a href="#">Right Link 2</a></li>
    </ul>
  </div>
