Question: How do i sum over indexes [Solved]

Hey mapleprimes

I am trying to get the sum function to give me n variables, well not sure how to explain it, so let me show:

sum(x__i, i = 0 .. 2)

I was expecting to get x__0 + x__1 + x__2

But instead i got:   3*x__i

Thanks for the help in advance :)


My problem is gone, but must be some weird character that is playing games with me or something
