2 motors controlled by one joystick

GBissell:
this might seem like an odd question but regardless, is it possible to use the style of code that i have been using to run the motors parallel at all times? if so does anyone have any advice how? Ive become stuck.

If you mean have the opposite side continuous rotation servos move forward and reverse together, then the below is a usual way where the pot value is mapped to 0-180 deg.

myservo1.write(n);
myservo2.write(180-n);
