Please:
  • Reduce the code down to a minimal working example (MWE) that reproduces the error. Note that this might actually solve the problem, but if it doesn't, then edit your post:
  • Format the code to be more readable.
  • Describe what is being run, what you expect, what you get.
And please use a more descriptive title than "I get an error, could you guys help me to figure out?"
