Search system, (Noob)

[Exilo]

Well, hello guys.
I am trying to just try to make a search system for my website.

I've followed this tutorial:

You must be registered for see links

And ended up with this code:

<?php
mysql_connect ("localhost", "*****","******")  or die (mysql_error());
mysql_select_db ("*****");
 
$term = $_POST['term'];
 
 $sql = mysql_query("select * from testtable where FName like '%$term%'");
 
while ($row = mysql_fetch_array($sql)){
    echo 'reported: '.$row['reported'];
    }
 
?>

However, I am getting "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/exilo385/public_html/adminpanel/search.php on line 9"

Now, I'm new with this, and I've tried to edit in line 9, but still not working.

Anyone have some help? Just so you guys can show me what's wrong?

Trying to search in "reported":
