C1_W2 Submitting Help

I completed the lab, and all the tests passed. But when I submit it, I get a 0% and the grader output is “There was a problem compiling the code from your notebook. Details:
name ‘MultiplyRow’ is not defined”

I’ve tried the ?forcerefresh=True, I tried restarting the kernel and running all the cells and saving and then submitting, I tried # grade-up-to-here. Nothing has worked. I finished the course, but this last faulty submission is holding me back from finishing.

@yp011235 Please let us use one thread for your problem.
