list-style-type not showing up in IE's

[decepticon]

Hi, im having a problem getting my bullet points to show up in IE6 and IE7.

The site in question can be located here (http://www.expandedgraphics.com.au/web/hds/).

As you can see in FF it looks how I intended to. However they are missing in IE's.

I have narrowed it down to a floating issue as well as left margin on the li as when I change my css to the following the bullet points then show ...

.nav li {
margin-left: 20px;
list-style-type: square;
}

However I want to achieve a simple horizontal navigation. Can someone please assist me in what I need to change.

Thanks in advance!

The easiest solution is to use a background image in the <li> and remove the list-style-type
