Need some help with links.

Hello,

this is the script that I'm using for the links...

<style type="text/css">
A:link {text-decoration: none;}
A:visted {text-decoration: color: red;}
A:hover {text-decoration: underline; color: red;}
</style>

but when I click on the link and go back to the page and mouseover the link, the color of the link stays blue. it doesn't change to red when it is off or when I mouseover. Can someone tell me what I'm doing wrong please

thanks

<style type="text/css">
A:link {text-decoration: none;}
A:visted {text-decoration: none; color: red;}
A:hover {text-decoration: underline; color: red;}
</style>

thanks
