change of the function definition in example fails

[rachelglenn]

Hi. I using the example with the integration math.sin(x[0]+x[1]+x[2]+x[3]) I inserted an intermediate function: ( I checked that it can be evaluated outside of my_func(x))

def my_func(x): yu = math.sin(x[0]+x[1]+x[2]+x[3]) integrand = P3_integrand_Eq2_c(x[0], x[1], x[2], x[3], wo, omegas, phase_type) return yu

I get the following errors:
