DIGIPOT_MOTOR_CURRENT Compiling error

Hi
I am trying to compile my marlin code so I can upload it to my printer and I keep getting an error.
The error I am getting is that it says that the 'DIGIPOT_MOTOR_CURRENT' was not declared in this scope.
This is in the Stepper.cpp tab of marlin

 void Stepper::digipot_init() {

    #if HAS_DIGIPOTSS

      static const uint8_t digipot_motor_current[] = DIGIPOT_MOTOR_CURRENT;

      SPI.begin();
      SET_OUTPUT(DIGIPOTSS_PIN);

      for (uint8_t i = 0; i < COUNT(digipot_motor_current); i++) {
        //digitalPotWrite(digipot_ch, digipot_motor_current);
        digipot_current(i, digipot_motor_current);
      }

    #elif HAS_MOTOR_CURRENT_PWM

      #if PIN_EXISTS(MOTOR_CURRENT_PWM_XY)
        SET_OUTPUT(MOTOR_CURRENT_PWM_XY_PIN);
      #endif
      #if PIN_EXISTS(MOTOR_CURRENT_PWM_Z)
        SET_OUTPUT(MOTOR_CURRENT_PWM_Z_PIN);
      #endif
      #if PIN_EXISTS(MOTOR_CURRENT_PWM_E)
        SET_OUTPUT(MOTOR_CURRENT_PWM_E_PIN);
      #endif

      refresh_motor_power();

      // Set Timer5 to 31khz so the PWM of the motor power is as constant as possible. (removes a buzzing noise)
      SET_CS5(PRESCALER_1);

    #endif

Here is the error message.

Arduino: 1.6.13 (Windows 8.1), TD: 1.33, Board: "RAMBo"

sketch\stepper.cpp: In static member function 'static void Stepper::digipot_init()':

exit status 1

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I was wondering what I need to troubleshoot to get this working?
Let me know if you need more information.
Thanks
