Iap For Game Currency - Quantity?

So I'm setting up an IAP for in-game currency, so users can buy more coins if they so wish, instead of earning them in the game.

I have the purchase button, and I have selected in-game currency.

But where do I specify the quantity?

Thanks.

 

off course you will need to setup coin action for every quantity.

 

Ohhhhhhh, I see.
So just set up a new Action, with the specified quantity, and use that to add it to the balance
Got ya.

Thank you.
