my php code does not insert

[Stephen Brown]

I have created my database on Hostmonster using the wizard and PHPadmin. And the database appears fine. I can add to it at PHPadmin. But I can not get this PHP script to work. I cam here because I thought maybe it was a MySQL problem.
/* put it in the database

$username="steve";
$password="password";
$database="_contacts";

mysql_connect("localhost", $username, $password ) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());

mysql_query("INSERT INTO 'data' VALUES('$first','$last','$email','$likeit')");

mysql_close();

/*mail($sendtome,$mesubject,$datamessage);*/

I even copied code from PHPadmin but it stil ldid not work.
Hope someone can help.
Thanks.
Steve
