Driver door latch on 2008 Mercury Milan

Cord that controls the door latch busted off, wont open from inside. Anyone have any idea how to fix it or how much it would cost to get it fixed?

Not sure if the cable is faulty or the latch where it mounts, or the door handle.

Can't figure pricing until you find out what's wrong. Figure maybe $125 in labor, plus parts.
