getting quotes

ok im trying to get quotes from my forum so users are able to quote other users posts...

what i came upwith is this

on the forumpgae display a quote button that has a form like so

   <form action="index.php?page=reply&id=<? echo $forumpostid ?>" method="post" name="quote">
        <input name="quote3" type="hidden" value="<? echo $getreplies3['postid'];?>" />
        <input type="submit" value="quote" />
      </form>

then on the action page display a textbox that shows the below code... the thing is nothing shows up in the textbox ??

<textarea id="inputforum" class="inputforum" name='yourpost' rows='5' cols='40'><?php if(isset($_POST['quote'])) {
                        $quote= $_POST['quote'];
					      
?>
