Please attach your worksheet, its hard to impossible to debug a picture.

One idea: For the 6i you have to type 6*i, otherwise i would be interpreted as imaginary unit!

I suspect the problem is that you typed the lower limit as 6 times i. This makes Mathcad think i is the imaginary number, the square root of -1. Try typing the lower limit as i*6 (i.e. i times 6).

I had the same suspection. But if he types 6 times i (with an explicit multiplication sign typed) it is not interpreted as imaginary unit. Thats the reason I suggested he should type 6*i (including the *) instead of just 6i.

Yes, I should have read your reply more carefully!
