If month column A, then return Qty column G

I’m trying to get a formula to show items in or out in a month. In column A I have dates (eg 01/01/20, 15/01/20), and then in column G I have QTY in (eg 15, 7 etc), and out in column H. I’d like to find month And return total value of G (eg in the above total of 22). Thanks, Will
