Sorry if this posts twice. Thanks everyone for the help.
The missing comma was the problem with the display; the missing
specification of the column at the start of the sql query was the
problem with getting the data from the column.
Again, thanks all who replied for the fast and excellent help.

Thanks for taking the time. I had suspected that earlier, but when I
put it in all sorts of OTHER stuff happened.
Then I saw your post and tried again. I saw that I had made another
mistake later on. So you've solved that part - thanks!.
Except....Except it doesn't pull the content from the db and substr it
to 200 characters. It pulls the id number and the title no problem, and
I am sure that $article['content'] points to the right place (or at
least it's named right) but it's just not getting the content:
if (!empty($where)) {
echo "
<ul>";
$article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
// humanize data
$article_id = $article['article_id'];
$title = $article['title'];
$content = substr($article['content'], 0, 400); // get first 200
chars
// print and see if we get, what we expect
// print "id=$article_id<br>title=$title<br>content=$content<p>";
// now make the real stuff
$table_of_contents[] = "<li><a
href='{$_SERVER['PHP_SELF']}?
a={$article_id}'}&title='{$title}'>{$article['title']}</a><br/
>$content<br /><a
href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
title='{$article['title']}'> ... [Read article]</a></li></li>";
}
}
echo "
</ul>";
Thanks in advance. . .
