C3_W1_Assignment GRADING prblm

i submit the lab and got the same output as the expected one but i got all 0’s and 0% in the final grade i finished all the weeks of probability for ml course i’m just stuck in week 1 lab assignment lab and when i check i get this note :
“There was a problem compiling the code from your notebook. Details:
name ‘comb’ is not defined”

Where are you using this comb variable or function, check inside in your implementation. Maybe it inside a loop and should not be there…

I sorted out and finish it, i used a function called comb but i didn’t defined it,
but weird the cell run normal and it didn’t gave me an error since the beginning.
anyway thanks for replying and ur time
