Sorry, that is the answer you've been giving, and I don't want that answer. The problem is that it says so in the contract.
I want to know, why did you quote zero? If you quoted zero, then you shouldn't have charged it. It is fraud. If you don't remember, it's on page 240 of the RFP.
Since my time is up, I can't ask anyone any questions, but I certainly don't want the answer that you've given in that book.
