Issue uploading Marling Firmware on RAMBo

Guys I need some help here.
For a long time I have used RAMPS on my Prusa I3 but I decided to make some upgrades, then I bought a RAMBo and installed it on my printer.
The point is that I can't upload the firmware (Marlin), I have choosen the right board and followed a youtube tutorial.
But It keeps showing this error:

stepper.cpp:1534: error: 'DIGIPOT_MOTOR_CURRENT' was not declared in this scope

How can I fix that? Thank you!

Did you find an answer to this? I am there right now!
Cheers
Alex

I found that a fix posted in the Repetier forum also works in Marlin

I was compiling Marlin 1.1.x on Arduino 1.8.2 for RAMBo 1.2d

I got this error:

'DIGIPOT_MOTOR_CURRENT' was not declared in this scope

I uncommented the line below in Marlin's Configuration_adv.h

#define DIGIPOT_MOTOR_CURRENT { 135,135,135,135,135 } // Values 0-255 (RAMBO 135 = ~0.75A, 185 = ~1A)

...and it compiles fine.
