Inventory "Apply" button

[hardrock14]

Hey party people!

I'm looking for a macro for an apply button. I'm creating an inventory and I'd like to have a column (column G) where I keep the quantity and another column (column F) where i can put a quantity change for each item and when I finish i can hit an "apply" button, which will add column f to column g and reset column g to all 0s or even blank might be better.

Any help would be appreciated thanks!
