_________index.php_____________

<?php

$db= mysql_connect("localhost","root","masood");
mysql_select_db("attendence",$db);

	 $result= mysql_query("select uname,upasswd from user",$db);
	while ($myrow = mysql_fetch_array($result))
	{
	 if(($uname == $myrow["uname"]) && ($upasswd == $myrow["uname"]));

firstly the preceeding line should probably be:

if(($uname == $myrow["uname"]) && ($upasswd == $myrow["upasswd"]));

		{	
	 		echo $myrow["uname"];
	 		echo $myrow["upasswd"];
	  	}
	}
?>
</body>
</html>

this give me error no 13, with uname,upasswd undefined, please help me out,
TIA

get familiar with the var_dump() and print_r() functions. for instance 
what does the following output:

$result= mysql_query("select * from user",$db);
while ($myrow = mysql_fetch_array($result)) {
	print_r( $myrow );
}

are the indexes 'uname' and 'upasswd' defined in each dumped array?
