[MOD HELP] ToC Block

Hi everyone. I've been working on a mod/block for eFiction to add a "Table of Contents" listing to the story listing pages using the "storyblock" hook.

I copied most of Tammy's viewstory.php code as pertains to the index (I've added "c" before most variables just to make sure there are no collisions), and it works great on my index.php "recent" block. However whenever I load it on the "listings" pages like browse.php?type=titles it wipes out all the other field (except for read count). I'm pasting my code below as well as a screenshot of what the page looks like when it tries to load the code.

You can see a full example of it working on this index page: http://lgtales.com/stories/index.php

modules/miscblocks/toc.php:

if(!defined("_CHARSET")) exit( );
$cinfo = dbquery("SELECT chap.* FROM ".TABLEPREFIX."fanfiction_chapters as chap WHERE sid = '".$stories['sid']."' AND chap.validated > 0 ORDER BY inorder");
$ccount = 0;
while($chap = dbassoc($cinfo)) {
  $tpl->newBlock("tocblock");
  $tpl->assign("cchapternumber", $chap['inorder']);
  $tpl->assign("ctitle", "<a href=""viewstory.php?sid=".$stories['sid'"]."&amp;chapter=".$chap['inorder']."">".$chap['title']."</a>");
  $tpl->assign("cprinticon", "<a href=""viewstory.php?action=printable&amp;textsize=$textsize&amp;sid=".$stories['sid'"]."&amp;chapter=".$chap['inorder']."" target="_blank"><img src="'".(isset($printer)" ? $printer : "images/print.gif")."' border='0' alt='"._PRINTER."'></a>");
   if($reviewsallowed) {
    $tpl->assign("creviews", "<a href=""reviews.php?type=ST&amp;item=".$stories['sid'"]."&amp;chapid=".$chap['chapid']."">"._REVIEWS."</a>");
    $tpl->assign("cnumreviews", "<a href=""reviews.php?type=ST&amp;item=".$stories['sid'"]."&amp;chapid=".$chap['chapid']."">".$chap['reviews']."</a>");
  }
  $tpl->assign("cwordcount", $chap['wordcount']);
  $tpl->assign("ccount", ($chap['count'] ? $chap['count'] : 0) );
  $tpl->assign("coddeven",  ($ccount % 2 ? "odd" : "even"));
  $tpl->gotoBlock("_ROOT");
  $ccount++;
}

I've stepped through the code and it seems to always happen when it calls "$tpl->newBlock("tocblock");" could this be a problem with TemplatePower and Nested Blocks? It kills the same information no matter where I place the tocblock data into the listings.tpl file

Here is a snapshot of a listing with ToC turned on, where it drops all the other data:

Here is the same listing with ToC turned off, that shows how/which fields should be populated:

Edit -- I've found a way to do what I wanted to do, but using a modified code that allows less control, (but I would DEFINATELY like to know if anyone can fix the above code):

if(!defined("_CHARSET")) exit( );

$cinfo = dbquery("SELECT chap.* FROM ".TABLEPREFIX."fanfiction_chapters as chap WHERE sid = '".$stories['sid']."' AND chap.validated > 0 ORDER BY inorder");
$ccount = 0;
$tocbloc="<OL>";
while($chap = dbassoc($cinfo)) {
        $tocbloc .= "<LI><b><a href=""viewstory.php?sid=".$stories['sid'"]."&amp;chapter=".$chap['inorder']."">".$chap['title']."</a></b>";
        if($reviewsallowed) {
                $tocbloc .= " [<a href=""reviews.php?type=ST&amp;item=".$stories['sid'"]."&amp;chapid=".$chap['chapid']."">"._REVIEWS."</a>";
                $tocbloc .= " - <a href=""reviews.php?type=ST&amp;item=".$stories['sid'"]."&amp;chapid=".$chap['chapid']."">".$chap['reviews']."</a>]";
        }
        $tocbloc .= " (".$chap['wordcount']." words)</LI>";
}
$tocbloc .= "</OL>";
$tpl->assign("tocbloc", $tocbloc);
