Help Please!

Checked many codes from Jquery samples unable to get the codes to work.

I need to replace html pages into one specific #CONTAINER, after having clicked the (<ul><li>Button 1</li>) this Button1 links to one html page. If successful I need to replace this Button 1 (page 1.html) with another (<ul><li>Button 2</li>) link and place page 2.html in the #CONTAINER.

I have tried .load, .replace, .switch, .append. All sample codes deal with either TEXT or color changes none show how to replace an html page.

Any help appreciated.
