I'm afraid your code is broken
<!-- BreadCrumbs -->
<td align="$stylevar[left]">
<div class="
bcrumbs">
<td class="smallfont">
<a href="$vboptions[forumhome].php$session[sessionurl_q]" accesskey="1"><strong>$vboptions[bbtitle] Forum Index</a>$navbits[breadcrumb]</strong> </div>
<!-- / BreadCrumbs -->
You are not closing those two data cells, and you also need to add a separate class "bcrumbs" to your CSS as per your code.
Here is a cleaner looking code
Code:
<tr>
<td class="alt1">
<!-- breadcrumb -->
<table cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%">
<tr>
<td>
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr valign="bottom">
<td width="100%"><span class="navbar"><a href="$vboptions[forumhome].php?$session[sessionurl]" accesskey="1">$vboptions[bbtitle]</a></span> $navbits[breadcrumb]</td>
</tr>
</table>
</td>
</tr>
</table>
<!-- / breadcrumb -->
</td>
</tr>
