First of all: You're using an deprecated API and your code is vulnerable to sql injections, so you should really take a few minutes to read Choosing an API and the accepted answer to How can I prevent SQL-injection in PHP?.

If you take a look at the mysql_connect documentation you will find that the third parameter is the password, so if your password is "root", you should change your code to:

$conn = mysql_connect("localhost","root","root");
