Command Button Macro

If you're sure that you have command buttons and you need VBA only, code for button "Loss" would be like :

Sub btn1_click()
Range("c21").Value = 100#
End Sub

Then, format your C21 cell to number, and give it 3 decimal number places to display 100,000.

You can do same way for all other cells, just change values.

For refresh :

Range("C9", "C13").ClearContents

And then repeat for all others, that's one option.

P.S. : to me It looks like you have just cells with thick border and not CmdButtons, maybe you should provide a sample here, picture doesn't tell much without file.
