Save Data

Hello everyone
I am using flash profession 8 and i’m trying to make a user comment collector.

I have 2 input text boxes called nameVar and messageVar
I have a dynamic text box called display
And a button that has this script in it

on (release) {
    display = nameVar + messageVar;

It works. But everytime i enter new details and click on the button i lose data inserted before. How can i save the values and add the new once on top
