So my program does what it shall, as I like to have some help on the calc I think I will leave it as is, that is input in a list so that the help can be printed.

That's right: the parametrisation, including range of integration, determines the surface while f describes the function that you want to integrate. A priori the two are totally unrelated. The same is true for the flux integral (where n is part of the surface definition and it will automatically come out of the parametrisation).
