Hi All,

I am trying to develop a quiz application based on MVC architecture using JSP and servlets. I have a frame where left side displays the questions and right side displays the set of buttons(total no of questions). When i click on "2" button, its not overwriting the left pane, instead its appending with the left one and displaying 1,2 questions. When i click on 3rd button, the left pane is not getting overwritten. In my servlets i am using request Dispatcher to forward to Jsp which will display the frame. Can you please hel out here. Below is my code

//Frame displaying left side question and right side buttons
