It's a newbie question, but if you could help I'd be very happy

When users purchase more than 1 product in in-app purchases, I want to increase the database to +1, so a user will be able to purchase a product 5 times. and will increase ( +1 ) for each product.

and when you gift this product to someone ( -1 ), it will decrease from the amount of the product you bought.

Do I need to use these functions?

What settings do I need to make to increase and decrease?

Can you help me ?
Thank You Soo Much
Kind Regards
I’m counting on you to help me with this.

No, you do not need those functions. You can do the math directly in the field:

current item count - 1 / current item count + 1.
