If you think about it, there's a pretty good reason why you can't use 
RAND inside a function. Imagine what happens when the code tries to 
solve such a function. The solver attempts to approach a solution by 
finding a series of points on each side that get nearer and nearer to 
the solution. If the function contains RAND, then the function is 
discontinuous everywhere, and that approach doesn't home in on a 
solution.

What you can do is write a macro instead of a function. You'll need to 
write your own loop to perform the sum() operation.
