Script help - Auto fill combo box from another combo box

I have been trying to follow instructions on how to create combo which auto pop another combo and intern that combo box auto pop other cells.  I used an existing sample script and tried to replace there var and objects with mine but it not functioning. Can someone review my script?

I have 6 cells goals, tactics, results, budget, action, tips. Both goals and tactics are combo boxes/drop boxes and the remain four are auto pop from the tact selection.

Please note i am very new to coding and trying my very best.
