Side Column problem on threads

[fov]

Hi,
Im trying to create a column down the right hand side of the page on all pages but below the nav bar which needs to span the whole page.
I have added the below code to the very bottom of the nav bar template:

$ad_location[ad_navbar_below]


<!--Columns -->
<table width="100%" border="0" cellpadding="0" cellspacing="0" align="center">
    <tr>

    <td valign="top">

<!-- /Columns -->

I have also added this to the footer

$ad_location[ad_footer_start]

<br />
<div class="smallfont" align="center">$vbphrase[all_times_are_gmt_x_time_now_is_y]</div>
<br />

$spacer_close
<!-- /content area table -->

<!-- ########################### Columns ########################### -->
</td>

    <td width="150" valign="top" class="page" style="padding: $stylevar[cellpadding]px;">
        YOUR CONTENT HERE
    </td>

    </tr>
</table>


<!-- ########################### /Columns ########################### -->

Its all working ok on the forum home and thread list but when viewing the thread and memberlist it indents as attached.

Is there anotherway or better way or way which works to do this?

Im using vB 3.8.1, no addons and this is the only change to style so far.

Thanks
