Arcade Drive Turning Problem

One of my students is trying to convert from Tank Drive to Arcade Drive. They have the following code. The robot will drive forward and backward just fine, but when trying to turn it will turn the opposite direction.

LeftFront.spin(vex::directionType::rev, (controller.Axis3.value() - Controller.Axis4.value()/2, vex::velocityUnits::pct);
LeftBack.spin(vex::directionType::rev, (controller.Axis3.value() - Controller.Axis4.value()/2, vex::velocityUnits::pct);
RightFront.spin(vex::directionType::fwd, (controller.Axis4.value() + Controller.Axis3.value()/2, vex::velocityUnits::pct);
RightBack.spin(vex::directionType::fwd, (controller.Axis4.value() + Controller.Axis3.value()/2, vex::velocityUnits::pct);

revesrse the motors and then reverse the direction types and it should work fine

Direction types? So go in and reverse all motors on the main page and then reverse the direction types where it says vex::directionType::rev?

Yep that will fix it.
