2 Warnings

Hi, when I try to access my php file I get 2 warnings:

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /disk3/daniel/public_html/client/test.php on line 8

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /disk3/daniel/public_html/client/test.php on line 36

My test.php file:

<?php
	include "mysql.php";
	$playername = $_GET["player"];

	$query = mysql_query("SELECT * FROM skills WHERE playerName = '".$playername."'");
	$query2 = mysql_query("SELECT * FROM skillsoverall WHERE playerName = '".$playername."'");
	
	while($row = mysql_fetch_array($query)){
		echo($row['playerName']);
		echo(" " . $row['Attacklvl']);
		echo(" " . $row['Strengthlvl']);
		echo(" " . $row['Defencelvl']);
		echo(" " . $row['Rangelvl']);
		echo(" " . $row['Prayerlvl']);
		echo(" " . $row['Magiclvl']);
		echo(" " . $row['Runecraftlvl']);
		echo(" " . $row['Constructionlvl']);
		echo(" " . $row['Dungeoneeringlvl']);

		echo(" " . $row['Cookinglvl']);
		echo(" " . $row['Firemakinglvl']);
		echo(" " . $row['Woodcuttinglvl']);
		echo(" " . $row['Farminglvl']);
		echo(" " . $row['Summoninglvl']);
	}
	while($row = mysql_fetch_array($query2)){
		echo(" " . $row['kills']);
		echo(" " . $row['deaths']);
	}
?>

How can I fix this?
