How to make a stat calculator?

[Aoexiak]

I'm trying to make a stat calculator for a game, however, I cannot seem to figure out the proper formulas to automatically add and deduct status points based on levels and stat points used. Below is a picture that I hope can help you understand what I am trying to accomplish. (If even possible.)

Hello

Welcome to MrExcel.

I'm very sorry, but I don't understand it. Can you please explain it in a much more clear way? Thanks.

I guess another easier way to explain this would be by showing you what I am trying to achieve. I've supplied a link with what inspired me to create this for my project, below.
RO Stat Calculator

On that page if you enter your 'Base Level' it will generate how many stat points you have at a maximum which you can use inside the boxes listed below (STR, AGI, etc etc).
I'm beginning to wonder if that's even possible with Excel...

Still very unclear to me, sorry. I wonder if anyone else understands the question and the purpose?
