Alt Category Background Image (One Category)

[Dax IX]

This is driving me nuts.

I'm trying to change the background gradient for ONE of my categories. I also have the Category Splitting template mod, and I'm editing the forumhome_forumbit_level1_nopost template.

Here's my code:

<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tbody>
    <tr>
        <td <if condition="$forum[forumid] == 36">class="tcatalt"<else />class="tcat"</if> colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">
            <if condition="$childforumbits">
            <a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
            </if>
            <a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
            <if condition="$show['forumdescription']"><div class="smallfont">$forum[description]</div></if>
            <if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
        </td>
    </tr>
</tbody>
<if condition="$childforumbits">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
    <tr align="center">
      <td class="thead" width="35">&nbsp;</td>
      <td class="thead" align="$stylevar[left]">$vbphrase[forum]</td>
      <td class="thead" width="175">$vbphrase[last_post]</td>
      <td class="thead" width="65">$vbphrase[threads]</td>
      <td class="thead" width="65">$vbphrase[posts]</td>
      <if condition="$vboptions['showmoderatorcolumn']">
      <td class="thead" width="120">$vbphrase[moderator]</td>
      </if>
    </tr>
$childforumbits
<tr><td class="thead" style="line-height: 0; padding: 0; margin: 0;" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>"><img src="$vboptions[cleargifurl]" alt="" width="1" height="12" /></td></tr>
</tbody>
</if>
</table>
<div style="padding: 0 0 16px 0;"></div>

And my CSS for the tcatalt background:

.tcatalt {background: #224887 url(http://www.teegopher.com/images/gradients/gradient_tcat_tg_alt.jpg) repeat-x top left;}

And this is my tcat CSS:

.tcat
{
    background: #224887 url(http://www.teegopher.com/images/gradients/gradient_tcat_tg.jpg) repeat-x top left;
    color: #FFFFFF;
    font: bold 10pt verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif;}

And I can't figure out why it won't change...

Thank you for any help...

Thanks!
