[SOLVED] PHP Query Help

[sl7ven]

Hi, I have my connection to the mysql server and database both connecting, my problem is this in php:

 

$query = "SELECT username FROM users WHERE username = '$un' AND pass = SHA1('$p')";
$result = mysql_query($query, $dbc);
$row = mysql_fetch_array($result);

 

I get this error:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource

 

Is there something wrong with the above code?
