I don't know how to expand an algorithm for over 100 cells

I have this excel with editable cells which modify the rest based of an algorithm. The file works fine, the problem is when I try to expand the cells in order to go over 100 registers. If I expand the first table to 10000 is okay, but whenever N3 is higher than 100, N10, N11 and N12 give error #?DIV/0!
I tried everything I know and I can't make it work. The file attached is the original one without modifications, as I don't know what I messed up.

Thank you very much for your help!!

Thank you for your response. Now N3 works just fine. The problem is when N4 > 100 which gives the error #¡DIV/0!
