Values adding inside a loop

Hello, I am trying to create some data by using several loops inside loops. The thing is that instead of giving me the result that it would be without loop (I have taken the data alone to check the result), it gives me added values. It seems that after the first loop it doesn't "reset" and the next results are wrong. Any idea why this can happen? Thanks in advance.

'Cuz that's what you wrote the loops to do...now that may not be what you intended for said loops to do, but...

As for "why?", probably because indeed inside an outer loop you've not reinitialized a variable that needs must be that either isn't existent prior to the execution without the loop or had an initially-zero value.

How would you expect us to diagnose anything specific without the code, however????

"Any idea why this can happen?"

Yes, several ideas. But you don't show us your code, so we will have to rely on our magical crystal balls to know what you code is doing. ooops, mine is broken today!
