Sub-item active state css

Hi
I'm developing a website, you can check it here - 94.46.8.45/~printcri/index.php/es/print-criativa/quem-somos

and I'm using accordeon CK menu. I've styled the menu on the template css, and everything is working as expected except for the active state on the sub-itens of the menu...i've tried several things in the css but without success.
Can you help me? Basically i want to give a style to sub-itens when they are active... (all the sub-itens will have the same style).

Follows the css for the menu i've created:

/*

---

MENU---- */
#menu {
float: left;
width: 235px;
}
#menu ul {
margin: 0px;
padding: 0px;
text-align: left;
}
#menu ul li {
display: block;
list-style-type: none;
list-style-image: none;
}
#menu ul li a {
display: block;
padding: 5px;
width: 225px;
text-transform: uppercase;
color: #FFF;
background-color: #333;
font-size: 14px;
border-bottom-width: 2px;
border-bottom-style: solid;
border-bottom-color: #FFF;
}
#menu ul li a:hover {
text-decoration: none;
}
#menu ul li:nth-child(1) a {
background-color: #f29400;
}
#menu ul li:nth-child(2) a {
background-color: #e2001a;
}
#menu ul li:nth-child(3) a {
background-color: #e2007a;
}
#menu ul li:nth-child(4) a {
background-color: #009ee0;
}
#menu ul li:nth-child(5) a {
background-color: #172983;
}

#menu ul li ul li:nth-child(1) a,
#menu ul li ul li:nth-child(2) a,
#menu ul li ul li:nth-child(3) a,
#menu ul li ul li:nth-child(4) a,
#menu ul li ul li:nth-child(5) a,
#menu ul li ul li:nth-child(6) a,
#menu ul li ul li:nth-child(7) a,
#menu ul li ul li:nth-child( a,
#menu ul li ul li:nth-child(9) a,
#menu ul li ul li:nth-child(10) a {
display: block;
text-transform: none;
color: #000;
font-size: 12px;
padding-top: 5px;
padding-right: 20px;
padding-bottom: 5px;
padding-left: 10px;
text-decoration: none;
float: left;
width: 220px;
background-color: #EEEEEE;
}
#menu ul li ul li a:hover {
display: block;
text-transform: none;
color: #172983;
font-size: 12px;
text-decoration: none;
background-color: #E3E3E3;
}

Hi
if you want to style the active items, use the class "active"
li.active
you can use firebug to help
