i just downloaded a login script and the code below is the php backend for the login. It is originally using md5 encryption and decryption for the password. For some reason I want to manage the password without encryption for now. my database has a member with login name and password. please see the line indicated with " ***" it keep complaining "databaseQuery failed"
I really have no more idea what could be wrong with that line of code, please help me. Thanks.

people commented that the codes are working. however in my case, it is not working. i tested it that it is connected to the database successfully. and that line of select statement looks right to me.
actually i think everything else is working (when i left both login and password blank it would send me to the login-fail.php page as supposed to) it looks like it is just that line of query got some issue.
thanks
