I don't know the program or what you are trying to do with it but the summation
$\sum_{n = 1}^nq_n^2x_n^2$
makes no sense. On the one hand you are treating n as a variable, on the other you are treating it as a constant.

You might try inputting the formula as
$\sum_{i = 1}^nq_i^2x_i^2$
or something.

It doesn't help that the dimensions are non-conformant for the summation either
