Pity that you did not address the relevance of the question: "If you remove the reached_your_destination zip file - Do you still get any message when you are 70 to 100 meters from the destination?".
The answer should have given some indication of understanding, how & where to move forward and be more accurate to the next step BUT, good for you that you used the Children_Left_Alert test as a properly hint.
I hope you close the ZIP's with the correct RAR version.
