Please Help, Been looking for a solution for weeks. current-menu-item issue

I’ve been posting about this for weeks and for whatever reason no one seems to know what the issue is, I’m dying for a fix…

When I add a style attribute to a the .current-menu-item that is in a drop down it effects the whole drop down list, not just the current menu item.

Here’s a link to site: ericbrockmanwebsites.com/dev4 (still very much a work in progress)

Here’s the CSS

#nav {
    display: block;
    margin-left: 575px;
    position: absolute;
    top: 78px;
    width: 400px;
}

#nav .menu, #nav .menu ul {
    list-style: none;
}

#nav .menu li {
    float: left;
}

#nav .menu a {
    float: left;
    display: block;
    color: #999;
    padding: 9px 10px;
    text-decoration: none;
    font-size: 14px;
    font-family: Helvetica, Arial, sans-serif;
}

#nav .menu a:hover {
    color: #ccc;
}

/* Styling for current parent item */
#nav .menu li.current-menu-item a, #nav .menu li.current-menu-parent a {
opacity: 0.5;
}

/* Styling for sub-menus */

#nav .menu li ul {
    position: absolute;
    width: 100px;
    left: -999em;
    margin-top:30px;
    padding-top:15px;
}

#nav .menu li ul li a {
    font-size: 11px;
    color: #999;
    width: 100px;
    border-bottom: 1px solid #ccc;
    text-transform: none;
}

#nav .menu li.current-menu-item ul li a {
display: block;
}

#nav .menu li ul li a:hover {
    color:#ccc;
}

#nav .menu li:hover ul, #nav .menu li li:hover ul, #nav .menu li.sfhover ul, #nav .menu li li.sfhover ul {
	left: auto;
}

Thanks in advance for any help!!
