Inserting text into a textarea

[Dragonfire2008]

I currently have this HTMl code...

<p><a class="insertCode" href="#">&lt;p&gt;&lt;/p&gt;</a> | <a class="insertCode" href="#">&lt;a target=&quot;&quot; href=&quot;&quot;&gt;&lt;/a&gt;</a> | <a class="insertCode" href="#">&lt;h1&gt;&lt;/h1&gt;</a></p>

and this javascript...

<script language="javascript" type="text/javascript">
	$('a.insertCode').click(function()
		{ 
   var htmltag = $(this).text();
   $('#codeArea').val($('#codeArea').val()+htmltag); 
   return false;
		})
</script>

I am trying to make those links into "buttons" that will insert code into my textarea. So far I have nothing happeneing, even the links still work...
