PHP - mssql

Hi. I have a table that contains lots of names in mssql. and i want to make a page where each of theese individuals can login with that spesific username and password. So my question is : what is the proper (best) command to use for sending and returning the info? <?PHP $link = mssql_connect($hostname,$username,$password); $dblink = mssql_select_db($dbname, $link); if ( $link && $dblink ) { $query = "select * from members where user = '$user' and pass = '$pass'"; $result = mssql_query( $query ); if ( $result ) echo "correct login"; else echo "wrong login"; } ?> This is not working... i have tried everything i can think of that can work but with no luck. So if someone have a solution for me... i would apriciate it :) (and yes i do have defined all the vars in the script they are just not that important here....) -Chris
