but i am copying and paste in the last line in the config file

come on man… you are missing a close brace } and a close bracket ]

start at the top of the new module you are adding and find the open braces { and match then with a close brace }

and then make sure that the confg.js modules section starts with a [ and ends with a ]

that way the code will be in a box like this one.
