How To Use Hover On mod_navigation??? [SOLVED]

Hello all :D . Trying to figure out how to set Hover to my main navigation module. So far the code for my navigation looks like this:

Code:

---

/* Nav Bar Rows */
ul
{
        margin:0 0 0 auto;
        padding:0;
        text-align:right;
        list-style-type:none;
}

a
{
        text-decoration:none;
        color:#c7bfbf;
}

.mod_navigation
{
        margin-top:-20px;
        margin-left:-20px;
        font-weight:bold;
        font-size:11px;
        color:#c7bfbf;
        line-height:22px;

---

I've tried inserting the string of

Code:

---

a:link {color:#}; a:visited {color:#}; a:hover {color:#}; a:active {color:#}

---

Into each area... including changing 'a' to '.mod_navigation' , '.hyperlink_txt', and 'ul' without any luck. Am I missing a step or maybe not inputting the code correctly or the wrong area??? Plz help! Thx!
