PHP mysql_num_rows()

Hey,

ich habe folgendes Problem:
Warum bekomme ich hier diesen Error?^^

Zitat

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\sh12rl\success.php on line 12

Mein Code:

<?php	session_start();	if(isset($_POST['Transfer'])) {    	$username = $_SESSION['username'];    	$pID = $_POST['uPlayer'];    	$betrag = $_POST['uBetrag'];    	$pSql = "SELECT * FROM accounts WHERE Name='".$pID."'";    	$sql = "SELECT * FROM accounts WHERE Name='".$username."'";    	$pResult = mysql_query($pSql);    	$result = mysql_query($sql);    	if(0 < mysql_num_rows($pResult)) {        	$pData = mysql_fetch_array($pResult);        	$data = mysql_fetch_array($result);        	if($betrag > $data['Geld']) {            	echo "So viel Geld besitzt du nicht!";        	}        	$data['Geld'] = $data['Geld']-$betrag;        	$pData['Geld'] = $datapData['Geld']+$betrag;    	}	}	else if(isset($_POST['Anlage'])) {    	$betrag = $_POST['anlage'];    	echo "Angelegt!";	}?>

Okay jetzt geht alles, wenn ich es per Localhost starte, aber wenn ich es Hochlade und mich einlogge:

Aber über localhost geht alles ?
