[SOLVED] How change a:active color in left sidebar

Found another thread with a solution that works ALMOST perfectly for changing active link color in the left sidebar.

td#left li.current_page_item a {
color: #99cc33 !important;
}

The only problem is that when I click on "Internet Marketing," (http://muzzmarketing.com/services) the entire list of second level links turn active instead of just "Internet Marketing"

Any suggestions? Thanks!
