Ammunition count macro

[Owastell]

Hello,


Completely new to using Macros in excel. I play a Role Playing Game called Shadowrun and I use excel to track my character info. I would like to create a button that when I click it subtracts ammo from my count and a second one that resets the count when I reload. For example, if I fire a 3-round burst from a 30-round magazine, it adjusts the count to 27. When I reload, I click that button and and it resets it to 30. I'd like more than one button that does the same thing for different amounts; ie: single shot vs bursts.

Thank you for any help you can give me,
Owen.
