W3_Ex4_Forward Propagation

Hello!
I’m having this error:


I’m probably importing parameters in a wrong way, but I’m stuck in here, so I would appreciate some help :slight_smile:
Thanks in advance!

take a look at what you completed earlier in initialize_parameters. you’ll see that parameters are indexed not by 1, 2, 3, but something else

“parameters” is a dictionary.
You index it using keys (a text string), not integers.
