The list-style-type is not visible
In Internet Explorer 7, an unordered list with items that has list-style-type set to circle and list-style-position set to outside, may not show the circle type you’ve set previously.

In order to show the type set above, you need to apply a padding-left to the proper tag. In most of the cases, a simple padding-left:16px; will work:
ul {
padding-left:16px;
margin:0;
}
ul li {
list-style-type:circle;
list-style-position:outside;
}
