Hi Andrzej,

Thx for your help, I think I understood where my error was.
To elaborate on this part:

As I explained in the reply to David, the problem is that my example was just a very simplified example of my real function, which depend on several variables and parameters, with some parameters dependent on another parameter. This function I have then to inject in another function, which I want to derivate which... I noticed that all this quickly gets a nightmare, I thus wondered about a method to keep every step the clearest possible.
Your evaluate looks interesting, but I just found out that I can use params[p_] instead of params.

Thanks, Johannes
