strange error

[nakkaya]

print "\nTotal Sites: ";
$sql = 'SELECT count(*) FROM sites';
$results = mysql_query($sql,$id_connect);
$count = 0;
$data = array();
while ( $row = mysql_fetch_array($results))
{
$data[$count] = $row;
$count++;
}
mysql_free_result($results);
print $data[0][0];
print "\nTotal Pages Indexed: ";

after this code i get
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/devil/server/engine_stats.php on line 14

but there is nothing wrong with the code

[MCANDREY]

I use the following code and works fine! ...

<?php
/ Connecting, selecting database /
$link = mysql_connect("localhost", "x", "x") or die("Could not connect");
//echo "Connected successfully";
mysql_select_db("cltbooking") or die("Could not select database");

print "\nTotal Sites: <br>";
$sql = 'SELECT count(ID) FROM agency';
$results = mysql_query($sql);
$count = 0;
$data = array();
while ( $row = mysql_fetch_array($results))
{
$data[$count] = $row;
$count++;
}
mysql_free_result($results);
print $data[0][0];
print "\n<br>Total Pages Indexed: ";

?>
