Tried it and it appears that nothing happens, I used n=4400 and then just n=10, it sat there processing for a couple of seconds and then...nothing.
Did I miss something? My formulas are 3 deep 'If' statements... nothing more than that but there are a lot of them, actually its not 19 million in one array but across 18 arrays, so its good that n is variable.
Thanks again for your attention.
