Hi, I'm trying to use solver, through a vba code,to create an efficient
frontier (an optimization process for many levels of constrain). While I run
it in a small spreadsheet It works very well, when I run this code in a
bigger spreadsheet it makes only the first loop (with a correct solution) the
it shows a msgbox saying something like "internal error or not enough flash
memory". Do you think the problem is in the code or, maybe, in the memory?

Thank you

p.s. if you want I can submit my code
