SQL Help - Newbie - php

Question

I'm picking up the pieces for a friend. His website used to work and pull featured products from his database, but it doesn't seem to be working. Its just showing the Error!!
Any help would be appreciated.... I'm not really up to date with SQL.
Here's the code:
<?php
require_once('const.php');
$link = dbConnect();
$query = "SELECT *
FROM vehicle_tbl, manufacturer_tbl
LEFT JOIN image_tbl ON vehicle_tbl.vehicle_id = image_tbl.vehicle_id
WHERE vehicle_tbl.manufacturer_id = manufacturer_tbl.manufacturer_id AND
vehicle_tbl.vehicle_feature2 = '1'
GROUP BY vehicle_tbl.vehicle_id
ORDER BY RAND()
LIMIT 1";
$result = false;
$result = #mysql_query($query, $link);
$fmain = false;
if (($result) && (#mysql_num_rows($result) > 0)) {
$fmain = #mysql_fetch_array($result, MYSQL_ASSOC);
#mysql_free_result($result);
}
$query = "SELECT *
FROM vehicle_tbl, manufacturer_tbl
LEFT JOIN image_tbl ON vehicle_tbl.vehicle_id = image_tbl.vehicle_id
WHERE vehicle_tbl.manufacturer_id = manufacturer_tbl.manufacturer_id AND
vehicle_tbl.vehicle_feature1 = '1'
GROUP BY vehicle_tbl.vehicle_id
ORDER BY RAND()
LIMIT 6";
$offers = false;
$offers = #mysql_query($query, $link);
function nextOffer() {
global $offers;
if ($offers && ($row = mysql_fetch_array($offers))) {
if (! isset($row['image_name'])) { // no image
$image = 'images/noimagesml.jpg';
} else {
$image = 'images/vehicles/sml/'.stripslashes($row['image_name']);
}
$title = stripslashes($row['manufacturer_name']).' '.stripslashes($row['vehicle_model']);
$price = number_format((float) $row['vehicle_price_pcm'], 2);
$id = (int) $row['vehicle_id'];
echo '<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td class="contenthead"><table width="100%" border="0" cellspacing="0" cellpadding="0">

<td width="11" height="40" align="left" valign="top"><img src="images/featre_left_hd.gif" width="11" height="23"></td>

</table></td>
</tr>
<tr>
<td class="contentpane"><table width="100%" border="0" cellspacing="5" cellpadding="0">

</table>';
} else {
echo 'Error!!';
}
}
?>

Display mysql errors like this:
mysql_query($query, $link) or die(__FILE__ . ' Line ' . __LINE__ . ': ' . mysql_error());
This should help you debug.
P.S. the mysql_* functions are deprecated - http://php.net/manual/en/mysqlinfo.api.choosing.php
