Thank you! :)
Well, you don't have to thank me, it was haruspex who gave you the formula.
However, I am not entirely sure you should be allowed to use this formula. TSny has tried to help you get this formula through a physical argument, you should try and complete the derivation. Otherwise you should know that the property is called a mean value theorem for harmonic functions and can be proven purely mathematically.
