Did you understand the advice? Have you simply dropped the first-attempt 
and gone looking for another canned-solution?

Whilst you seem to be on-the-right-track, there is a definite error in 
the algorithm/the code.

What debugging did you perform?

Do you only assume, or can you see example (pertinent) values during 
each "pass" (time through the loop)? If not, why not?
