Help with Tempplates & SQL Queries

I'm writing a hack (ha! If you can even call it that - I'm not that talented)...and basically, I'd like to use SQL queries in the same format as vBulletin - since that seems to be the most logical thing to do...however, I can't get it to display more than one entry...any advice? I'll obviously need a while loop, but I'm not sure how to format it...

Here's what I have (which produces an error):

$query2=$DB_site->query_first("SELECT * FROM savethreads WHERE saveuser='$username'");
$result = mysql_query($query2,$DB_site);
while ($row = mysql_fetch_array($result)) {
	$savethreadid = $row["savethreadid"];
echo("$savethreadid");

Any thoughts?

Oh, also: I've created a custom template which is pulled onto a custom PHP page in my forums directory (thanks JimF! )...however the template displays first, with all my queries and their results below it all - how can I stick it in the middle of the template? I don't recall seeing actual queries used in any of the other templates...so I know there must be some other way.

Thanks!

btw, what is this hack?

It's called the "Save Threads" hack That alone should explain it...hehe.

If I can just figure out one or two more things, it'll basically be ready for release!
