loop "for" with "while"

[maria87]

hello,

I have problem with my program (I dont know very good Mathcad). I'm doing a program with loops "for" and it works perfect, but I put a cycle "while" and it doesn't work.

I think my program is not good but I have no more ideas. Can you help please?

I attach the worksheet (leflt: only "for", right: with "while"). thanks you very much
