Simulate data using Command Button

[ncaravela]

Hi everyone, it's been a while.

I have an excel worksheet where i need to calculate some values (the formulas are not inserted yet). However i need what i believe to be an easy help form you.
I have a command button to show the result but i can't get the vba code to make it work.

Basically i need to insert soma data in the white cells, then click the command button so that the results show up in the blue cells.

Please look at the attached file.

Thanks in advance.
