You can add it in the Sheet column for price calculation. ---

Do you mean in the column where I “put” the price of the item ? Or in another column ? ---

I mean you should create a new column in your Sheet, let’s say “Final price”, then calculate the price using arrayformula. > [@Tutorial: Arrayformula in Google Sheets, good practices & how to overcome Arrayformula restrictions with scripts](https://community.glideapps.com/t/tutorial-arrayformula-in-google-sheets-good-practices-how-to-overcome-arrayformula-restrictions-with-scripts/9727): > > Hi, Today I will show you the script that can make copying formulas down work, when it does not work with arrayformula.

It works also if I use Glide table ? ---

So,if I understand well : in the same glide table than the items, I add a column “Final price” and I calculate this price with an array formula ? So I had to create a button with an action " calculate" ( because it seems to me that if I use the buy button I can’t modify its function)? My items needs a row Id so ? If I add another item, where do this result is ? In which sheet ? Sorry, I don’t see in which “area” the result is temporary placed… Sorry for all these questions and thanks for the answers ---

As far as I aware, you must use a Sheet column in order to utilize the Buy Button, due to technical privacy concerns. That’s why I recommended using arrayformula to calculate it whatever ways you want inside the Sheet. It would be placed in whatever sheet serves as the base for you to built the screen which places the buy button on.
