Need help won't display menu in Internet explorer

Ok on the company website I work for the menu won't display the menu on the home page and contact page. But the product, service, calculators page work fine.
I believe it has something to do with the css code. Any help is much appreciated.
website = http://www.bbhydraulics.com
works fine in firefox.

This shows the menu

<style type="text/css"><!--
#page6 #main .box .border-top .border-right .border-bot .border-left .left-top-corner .right-top-corner .right-bot-corner .left-bot-corner .inside #content .wrapper .mainContent .row-1 .box1 .inner h5 {
	color: #FFF;
}
--></style>

Code (markup):

This doesn't show menu

<style type="text/css"><!--
#page1
 #main .box .border-top .border-right .border-bot .border-left
.left-top-corner .right-top-corner .right-bot-corner .left-bot-corner
.inside #content .wrapper aside .box2 .border-top .border-right
.border-bot .border-left .left-top-corner .right-top-corner
.right-bot-corner .left-bot-corner .inner table tr form td table tr td {
    color: #FFF;
}

Is there something I need to add to the html files to show code correctly in Internet explorer 7 and higher?

 

I now think it has something to do with the .nav css code

.box nav {
			background:url(../images/nav-bg.gif) 0 0 repeat-x;
			overflow:hidden;
			margin-bottom:1px;
			height:48px;
		}
			.box nav ul li {
				float:left;
				background:url(../images/divider.gif) no-repeat 0 0;
				padding-left:1px;
			}
			.box nav ul li.last {
				width:145px;
			}
				.box nav ul li a {
					float:left;
					font-size:13px;
					color:#fff;
					text-decoration:none;
					width:148px;
					text-align:center;
					height:47px;
					line-height:47px;
				}
				.box nav ul li a:hover, .box nav ul li a.current {
					background:url(../images/nav-bg-act.gif) 0 0 repeat-x;
				}

That was the problem I just had to add the .nav box into the css style code in the index file.

 

well I am stupid I was looking in firefox. I still need help

 

well I fix it but don't know why it work. Copy the web pages that work into the ones that didn't.

 

did you fixed your problem?

 

Thanks for asking. Yes I fix it just copy the web pages that were working and put that code into the other web pages. Very strange because it all the same code
