Can't get data from DB [Resolved]

PHP Code:

---

echo "<font face=tahoma size=1 color=#FFFFFF>";
$un=mysql_query("SELECT username FROM udb WHERE rank='Admin'") or die(mysql_error());
echo $un; 


---

All I guet is "Resource id #3", and I don't know what that means, nor have I been able to find a solution for it.

After doing the query you need to take data out of it. Read this page which walks you through the mysql_result() function.

Thanks.
