Mekanism Peripheral

Im trying to get the energy stored in an Elite energy cube from mekanism and im having trouble with one of the methods in it. The method is getMJStored(direction) and i have tried every direction from top bottom left right too east south north and west and none of these work so do any of you guys know what this "direction" variable is?

You wrote these as strings, right?

Yes i did write them as strings

Don't know if this will work, but have you tried "unknown" for the direction?
