CSS Link Colour Help?

Hey Guys,

I have a small problem:
My problem is that I have some text links as a menu and when it goes to a page I want the link colour of that clicked link to stay RED on the new page it went to and when I click another link I want the first link to go back to it’s normal colours. And the new link colour to change to RED and stay RED.

That’s what I am having trouble with - all my roll overs and :active, :visited etc… all work fine I just can’t get the above to work dynamically. ( I have alot of pages! ) and the menu is mostly a php include.

Cheers,
George
