How to use apsheet to add more than 1 item in form

[Odiez]

This is the first time I need to do something like this to work in app sheet

On my one screen, I have The following data to input so it saves to Google sheet. this is my form Im using

_rowNumber= no input
Nom=auto input (key and label)
Datum= todaysdate
Kaart=type(price)
Kontant=type(price)
Prys=type(price)
Ontvang=type(price)
Kleingeld=type(price)
Francois=type(price)
Kotie=type(price)
Item=Text

Is it posible to do the following in apsheet, if so how do I do it

It must ask how many items there is, so if there is 3, it must then let me add a price for each one and the item for each one, then it must add the price together so when using received and back it must use the total of all prices.
