i have done a calculatior, that have a nicely look, u can check it in my signature, but isnt for rank, is for level, but maybe i can add also the rank so make a program togeather that can do both thinks
EDIT!
I HAVE FOUND 2 BUGS!!
fisrt (well, maybe not a bug) the messagebox if u put no value, apparears 2 times and if u click on calculate ships, u can click between one of the check box(the ones in where u can only select one).
here i let u a vid with that bug.
EDIT2: u can also create a funcion like in my program, the actual rankpoints u need, and the rankpoints needed, so u dont need to calculate it
