Week 3 Exercise 8 - nn_model -- parameter error

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

I have written the following code to define parameter but results error. please help
parameters = initialise_parameters(n_x, n_h, n_y)

A2, cache = forward_propagation(X, parameters)
cost = compute_cost(A2, Y, parameters)
grads = backward_propagation(parameters, cache, X, Y)
parameters = update_parameters(parameters, grads)

NameError Traceback (most recent call last)

262 t_X, t_Y = nn_model_test_case()

That is not how that function’s name is actually spelled. It is initialize_parameters. “z” != “s”, right?
