Miért nem működik a lenyíló menü?

Ezt a kódot korábban már használtam sima html lapnál, de most a php-ba nem akar működni, a menük a helyükön vannak de nem akarnak lenyílni.

<style type="text/css">

a:link {

color : #CCCCCC;

text-decoration : none;

}

a:visited {

color : #CCCCCC;

text-decoration : none;

}

a:hover {

color : #FFFFFF;

text-decoration : none;

}

a:active {

color : #CCCCCC;

text-decoration : none;

}

#dropmenudiv{

position:absolute;

border:1px solid black;

border-bottom-width: 0;

font:normal 8pt Tahoma;

line-height:18px;

z-index:100;

}

#dropmenudiv a{

width: 100%;

display: block;

text-indent: 3px;

border-bottom: 1px solid black;

padding: 1px 0;

text-decoration: none;

font-weight: default;

}

#dropmenudiv a:hover{ /*hover background color*/

text-decoration:none;

background-color: #6A6A6A; /*menü szine*/

}

</style>

Mi lehet a gond?
