trouble with lists

on this page: http://staging.dmu.edu/com_2/do/ My lists are not showing bullets. Ive tried using an image, and now im just trying to get a regular circle bullet. Its not showing up in ie7 or ff on a pc. Heres the css:

#content ul {
margin:15px 15px 15px 40px;
padding:0;
list-style-type:circle;
}

#content li {
padding:0;
margin-bottom:15px;
}
