I have implemented what you suggested. But now I am getting an DB error

Code:

Error Number: 1054

Unknown column 'MCS20145B41' in 'where clause'

UPDATE monthly_due set md_due = md_due - 5500, md_paid = md_paid + 5500 WHERE md_work_id = MCS20145B41

Filename: F:\xampp\htdocs\foo\system\database\DB_driver.php

Line Number: 330

Why is this happening?
