It would be helpful to see what you have already (unless it came from Google, in which case forget it

), but here is a first attempt:

I am not strong on nested genitives, which we have here, so definitely wait for more input.
Also bear in mind that there is more than one correct way to say any given thing, so someone might come along with a completely different suggestion that totally blows this one away.
