Hi @Zabihullah_Buda

Are you sure you’re not doing the things in “Important Note on Submission to the AutoGrader” at the top of the assignment? Especially, the “You are not using any global variables inside your graded exercises. Unless specifically instructed to do so, please refrain from it and use the local variables instead.”?
