Array function is not working [SOLVED]

UPDATE:
Got it working thanks to all your guys' help! +1 Karma for all. There was just no boolean logic to change the state back to the original state once a sensor was tripped and the function executed. A very valuable lesson learned!

IDE v1.8.5

#include <NewPing.h>
#include <L298N.h>
