I'm having trouble with the bullets on the subcategories. I've added the code

a.category-subs-text, a.category-products-text {
display: list-item;
list-style: circle inside url(../images/bullet3.gif);
}

to the CSS but the bullets are not displaying in FF (mac). FireBug is installed and the 'display: list-item;' shows up as strike-through.

What am I missing?
