Dynamic label creation in Panel

Hi Friends,
I have 2 webpages Pages A,B.
In Page A,I got a linkbutton which redirects to pageB. 
I will fill a textbox in page B and clicks submit button.,then again it should redirect to PageA with text(from textbox in pageB) and user session (name in pageB) and display in dynamic label of page A (label is available in panel of PageA).
this process is cyclic and each time i enter a text from page B,it should create a new label in page A,without removing old label.
 
My Issue is when I write a new text in page B,its removing old comment and replacing with a new one.and that too label availabe is a static one(I dragged from toolbox).
