MySQL or PHP problem

[AttackBunnyPro]

I'm attempting to create a login script, but I can't seem to use mysql_num_rows or mysql_fetch_assoc. Here's my script:

 
<?php
$username=$_POST['username'];
$password=$_POST['password'];
if(!$username || !$password){
   header("Location: http://www.attackbunnypro.x10hosting.com/admin/");
}
$username = stripslashes($username);
$password = stripslashes($password);
$link = mysql_connect("localhost", "username", "password");
mysql_select_db("database", $link);
$result = mysql_query("SELECT * FROM table", $link);
$count = 0;
while ($line = mysql_fetch_assoc($result)) {
     $count++;
}
if($count == 1) {
  //actions
}
?>

It gives me this warning:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/abp/public_html/admin/login.php on line 14

If I use mysql_num_rows() instead, I get a similar error. Other alterations to mysql_num_rows script, but nothing major.

I looked at phpinfo(), and it has this:
MySQL Support: Enabled:
Active Persistent Links 0
Active Links 0
Is that the problem? If so, how can I fix it? If not, what am I doing wrong?

Try this. I'll also add in some debugging code.

<?php
$username=$_POST['username'];
$password=$_POST['password'];
if(!$username || !$password){
   header("Location: http://www.attackbunnypro.x10hosting.com/admin/");
}
$username = stripslashes($username);
$password = stripslashes($password);
mysql_connect("localhost", "username", "password") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());
$result = mysql_query("SELECT * FROM table") or die(mysql_error());
$count = 0;
while ($line = mysql_fetch_assoc($result)) {
     $count++;
}
if($count == 1) {
  //actions
}
?>

Thanks a ton!

You're very welcome. If you don't mind me asking what was the problem? I put the mysql debugging stuff in and took out the mysql link. Mysql links aren't necessary. When you don't use them, the connection is automatically closed.

I'm guessing it was just the link. It worked fine without it.
