C4W1 Z's Convolution_model_Step_by_Step

Hi,
I’m stuck in the Convolution_model_Step_by_Step Exercise 3 - conv_forward, i read all that i found about this exercise but i can’t find the error.
This is the message that i got:

I revised the last functions, the start and the end in the loops, i tried everything comment that i see here and nothing works, please help me

There are quite a few details in that function and many ways to get it wrong. It’s a bit hard to diagnose just from the wrong answer. The best way to debug is to start by reading this post from mrgransky that describes in words the details of how the algorithm works.

I already read this post and i have tried all that it’s say but nothing change the error, even i wrote my code again following the post but it didn’t change.

Please check your DMs for a message from me about how to proceed. You can recognize DMs (direct messages) by the little envelope icon.
