The result of your query is being saved into a variable called $res454, you then pass a vraible called $result454 to mysql_fetch_array().

You might also want to check the query actually worked before trying to use it. The way you have your code logic now is pretty poor coding practice.
magallforever, It is always best to print the errors to browser (in testing servers) when you are executing a query. Try to run this code and check what are the erros it is showing.

[code]

<?php
$connection = mysql_connect(localhost,zack_rpg,omfgg212) or die ('Connection Failed');
$db = mysql_select_db(zack_rpg,$connection) or die ('Db selection failed');
$sql111 = "SELECT * FROM stats WHERE id='$_COOKIE[id]' ";//Put it in single quotes if it is a number.
$res454 = mysql_query($sql111) or die ($sql111.":".mysql_error());
$res1 = mysql_fetch_array($res454);
$mana = $res1[mana];
$level = $res1[level];
$ladd = $level * 20;

if($mana < $ladd){
$sql = "UPDATE stats SET mana = $mana + 2";
$result = mysql_query($sql);
}else{
die();
};
?>

[/code]
