Why is my a:active not working?

I have a navigation menu that is part of my pages as an include and I have it styled so the color changes on rollover and when it’s active. The only problem is that it is not changing when it is active. Does anyone know why this isn’t working? Here is my css code:


#menu {
float:left;
margin:15px 0px 0px 0px;
padding:0px 0px 0px 0px;
}

#menu a {
font-size: 16px;
text-decoration:none;
color: #333333;
font-family: Arial, Helvetica, sans-serif;
font-weight: 800;
margin:0px 0px 0px 35px;
padding:0px 0px 0px 0px;
}

#menu a:visited{
color:#333333;
}

#menu a:hover {
color: #b20000;
background-image: url(../images/indicator.jpg);
background-position:left;
background-repeat: no-repeat;
}

#menu a:active{
color: #b20000;
background-image: url(../images/indicator.jpg);
background-position:left;
background-repeat: no-repeat;
}

Here is my html code:


<div id="headWrap"><a href="http://www.ts24.com/GarbageBin/index.cfm"><img src="images/tsExpectMore.jpg" alt="Travel Solutions - Expect MORE." width="241" height="43" border="0" align="middle" class="logo"/></a>
<div id="menu"><cfif variables.pageNo is 1><a href="http://www.ts24.com/GarbageBin/company.cfm" title="Travel Solutions - Company"> &nbsp;&nbsp;Company</a>
        <cfelse>
        <a href="http://www.ts24.com/GarbageBin/company.cfm" title="Travel Solutions - Company">&nbsp;&nbsp;Company</a>
      </cfif>
      <cfif variables.pageNo is 2>
        <a href="http://www.ts24.com/GarbageBin/services.cfm" title="Travel Solutions - Services">&nbsp;&nbsp;Services</a>
        <cfelse>
        <a href="http://www.ts24.com/GarbageBin/services.cfm" title="Travel Solutions - Services">&nbsp;&nbsp;Services</a>
      </cfif>
      <cfif variables.pageNo is 3>
        <a href="http://www.ts24.com/GarbageBin/resources.cfm" title="Travel Solutions - Resources">&nbsp;&nbsp;Resources</a>
        <cfelse>
        <a href="http://www.ts24.com/GarbageBin/resources.cfm" title="Travel Solutions - Resources">&nbsp;&nbsp;Resources</a>
      </cfif>
      <cfif variables.pageNo is 4>
        <a href="http://www.ts24.com/GarbageBin/news.cfm" title="Travel Solutions - News">&nbsp;&nbsp;News</a>
        <cfelse>
        <a href="http://www.ts24.com/GarbageBin/news.cfm" title="Travel Solutions - News">&nbsp;&nbsp;News</a>
      </cfif>
      <cfif variables.pageNo is 5>
        <a href="http://www.ts24.com/GarbageBin/contact.cfm" title="Travel Solutions - Contact">&nbsp;&nbsp;Contact</a>
        <cfelse>
        <a href="http://www.ts24.com/GarbageBin/contact.cfm" title="Travel Solutions - Contact">&nbsp;&nbsp;Contact</a>
      </cfif>
    </div>
</div>

The second code is the code that is in my include file. Thanks!
