<?
@ $db = mysql_connect("localhost");
mysql_select_db("egycds");
$query = "SELECT gameid FROM newpcgames";
$result= mysql_query($query);
$num_recs = mysql_num_rows($result);
$first_rec = ($first_rec) ? $first_rec : 0; //if rec is passed in, use it,
$max_rec = 50;

$test_tr = mysql_query("select * from newpcgames order by gameid desc LIMIT 
$first_rec,
$max_rec");
while($record = mysql_fetch_array($test_tr))
{



   echo "
                               <TR onmouseover=\"this.bgColor='000000'\"
