The Isis Adventure

I have the equation by somehow solving the compartment but the numbers from the first part don't get small enough to apply to RP. I have Clues one and 2 from www.isisadventure.co.uk and those don't mean anything to me at this point yet. Any hint to get me in the right direction appreciated. Don't want to be stuck with a beautiful expensive paperweight.

Once you understand all aspects of the "equation" then the numbers do work (unless the equation has changed since I solved mine).
