Course 1 Week 2 Assignment 5 - AssertionError: costs

I keep getting this Assertion Error regarding the cost, although i pass all the test up to this point (so everything before the model function). I have no idea where my mistake is…

Please provide the code of your model before we can help.

Hi @chger, there is a type in your parameters (cost should be costs). That should solve the issue. Could you remove the code snipit as we do not want it to stay posted on the platform?

Thank you! Now it’s working!
Yep, I will do so.
