This exersice have logical issue. We define function move() by calling two functions moveForwards() and trunRight()
BUT
we never call function move(). And this is where the logic error occure: if you only define function you pass exersice, but if you define and call it you fail test. But only defining function doesn't make move so this excersice omite important part of calling the function.

for those asking about the tracker, since "moveforwards" and "turnright" does not mean anything to Python, the tracker exists to serve as a proxy test to see whether you moved forward or moved right the correct number of times.
