Try to add return false ; at the end of process function.

:point_right: By making your button a "submit" type, you've given it two functions: One is the explicit click handler that calls process(), and the other is the default submit functionality of submitting your form data and then reloading the page (and thus erasing the new elements).

To avoid the second action, just declare your button as a "button" type:

      <button type="button">Display</button>

Then each click adds a new DIV to the compile section (you may want to limit that to just one time).
