Checking for errors within this popup code

[Champster]

I can't figure out what I'm missing. I've attached a image to display the error I'm getting.

The first photo is the error I'm getting and the second photo is basically an illustration of where I would like the drop menu to start to list each forum of my site.

Thanks for your help in advance.

PHP Code:

<if condition="$show['popups']">
    <!-- start vBMenu control element -->
    <table class="tborder" cellpadding="4" cellspacing="1">
    <tr>
        <td id="ForumMENU" class="vbmenu_control">
            <a href="#ForumMenu">Forum Menu</a>
            <script type="text/javascript">
            <!--
            vbmenu_register("ForumMENU");
            //-->
            </script>
        </td>
    </tr>
    </table>
    <!-- end vBMenu control element -->
 
    <!-- start vBMenu popup element -->
    <div class="vbmenu_popup" id="ForumMENU_menu" style="display:none">
        <table cellpadding="4" cellspacing="1" border="0">
        <tr>
            <td class="thead">Forums</td>
        </tr>
        <tr>
            <td class="vbmenu_option"><a href="http://www.mysite.com/forums">Main Forum</a></td>
        </tr>
        <tr>
