In the “conv_forward” graded function, there’s a commented section like so:
"
# for i in range(None): # loop over the training examples
# for h in range(None): # loop on the vertical axis of the output volume
# Find the vertical start and end of the current “slice” (≈2 lines)
# vert_start = None
# vert_end = None
# for w in range(None): # loop on the horizontal axis of the output volume
# Find the vertical start and end of the current “slice” (≈2 lines)
# horiz_start = None
# horiz_end = None
"
The second highlighted “vertical start” should say “horizontal start”.

This is the starter code inside conv_forward:

    # for i in range(None):               # loop over the batch of training examples
        # a_prev_pad = None               # Select ith training example's padded activation
        # for h in range(None):           # loop over vertical axis of the output volume
            # Find the vertical start and end of the current "slice" (≈2 lines)
            # vert_start = None
            # vert_end = None
            
            # for w in range(None):       # loop over horizontal axis of the output volume
                # Find the horizontal start and end of the current "slice" (≈2 lines)
                # horiz_start = None
                # horiz_end = None

Oh! I must have accidentally changed it then. Thanks for letting me know and I apologize for the misunderstanding.
