$querysrting variable. should concatenate strings: 

$sql = mysql_query("select user_id,                            first_name,                            last_name,                            birth_date,                            specialization,                            registered_date                     members $querysrting") // here

should this:

$sql = mysql_query("select user_id,                            first_name,                            last_name,                            birth_date,                            specialization,                            registered_date                     members".$querysrting) // here
