change these two lines to
title='{$article['title']}'>{$article['title']}</a><br />".
substr($article['content'], 0, 200)."</li>";

I did that and now it reads this:
if (!empty($where)) {
echo "
<ul>";
$article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
$table_of_contents[] = "
<li><a href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
<li><a href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
title='{$article['title']}'>{$article['title']}</a><br />".
substr($article['content'], 0, 200)."</li>";
}
}
\
Which doesn't kick back errors but also does not pull any
$article['content'] - it leaves a line break but no text is being
inserted from the content row.
