I removed some of the code but it doesn't work anymore. What's the minimum code I have to add to make it works ? I don't really get response and callback terms in ajax ? I'm only interested in ajax now to be able to work with session values with javascript. Now when I click on Say hi link, I only get messagge box with value "undefined".
