Not Being Able To Click Things In My Container (HTML/CSS)

[BreShiE]

Hey guys, I have a website which I coded completely myself (well the visual aspects, the comments script I gave credits to). But anyway, I can't click inside my container for some reason and I was wondering if someone can help me find out why.

Container CSS:

Code:

#container {
position:relative; z-index:-1; left:15px;
margin: 0px 0px;
height: 590px;
width: 75%;
background: url(http://breshie.com/test/images/container.png);
border: 1px solid black;
border-top: 0;
border-bottom: 0;
color: #fff;
text-align: center;
overflow-y: scroll;
overflow-x: hidden;
}

#container a:link {
color: #00CC99;
}

#container a:visited {
color: #00CC99;
}

#container a:active {
color: #00CC99;
}

#container a:active {
color: #00CC99;
}

If you need/want any more information, then just ask.
