GPS Sensor not detecting properly

#1

I need some help in gps sensor…in my skills when I program it to do rollers, it keeps driving forward and doesn’t stop. I debugged it and tried it from (0,0) to (0,20). It still did the same thing and kept driving forward. What should I do?

Here is my code:

For getting coordinates, these are the quadrants i’m using

(Note that it helps to include the full text of your code between two sets of three ticks ```)

Is this all of the code? I don’t see where you tell the robot to stop.

Drivetrain.stop();

I will try adding the stop… just realized i didn’t add that.
