In the IE browser, it looks exactly the same and in Chrome the bullets show.
Despite the errors in the CSS, as mentioned above, the code you have posted works the same in IE8, Chrome and Firefox - the bullet is hidden in all browsers. So it would seem there is code elsewhere that is overriding your list-style-type?!
