I see wats wrong,

<td id="1" class="vbmenu_control"><a href="#1">Drop down</a>
<script type="text/javascript"> vbmenu_register("extra"); </script></td>
<!-- dropdown end -->
here vbmenu_register"1" not (extra). you put extra where u have dropdown

and in the second code you suppose to replace ---->NAVBAR POPUP MENU<--
with the second code, dont write the second code under it.as u did in ur 2nd NAV BAR.

the first one should look like this
<td id="1" ><a href="#1"><b>Extra's</B></a>
<script type="text/javascript"> vbmenu_register("1"); </script></td>

try it this way ,works for me.
