Arduino Engineering kit drawing robot


I have an issue during running the live script of task 3 in drawing robot,

I already attached a screenshot so anyone can help, please?

counts = xyToCounts( .... is a function you create and is detailed out in the course curriculum that comes with the kit.

Make sure you have created the function before running that section of the code. Instructions on how to create are included in '4.3 Move to specified point' part from the content.
