Disappearing text?

[EvoloZz]

Hey again, and sorry if I am asking too much, I don't know any better way to learn.
But I created 2 huds with some text, so I want the first hud disappear slowly after 20 sec (for example like "Visit killtube.org" on K~ servers) , then it shows the second hud and it disappears after 20 sec also, so it would just loop between two huds. :P
My setup:

ShowText2()
{
	
	if(!isDefined(self.text_left))
	{
		self.text_left = newClientHudElem(self);
		self.text_left.x = 259; 
		self.text_left.y = 35; 
		self.text_left.alignX = "left";
		self.text_left.alignY = "middle";
		self.text_left.sort = 1; 
		self.text_left.alpha = 1;
		self.text_left.fontScale = 1.7;
		self.text_left.archived = true;
		self.text_left setText(game["hud_text2"]);
	}
}

I will create second HUD later :P

Thanks!
