As already written above - you need to define variable i

Thats also what the error message is telling you.

I am not sure what you are trying to achieve, but maybe you are looking for something like this:

You could also use

for the same result.

If this is, as I think, what you are looking for and if you need that kind of calculation more often you may consider writing a small utility function like this, which you can use on various vectors of arbitrary size and without having to define ranges, etc.:

In real Mathcad you would also have to define i (presumably as a range)

Don't post just pictures, attach your worksheet
