One-click button can update for empty field? And how move the value in another table?

Hello Partners,
I;m new in your community. Hello :slight_smile:

I have 2 small issues and I don’t know how to solve it. Maybe you can support me.

  1. One click button is nice solution. I would like to use it by 2 buttons. When user will click ADD button value will record in temporary field and button will hide. When value is not empty will apear button REMOVE and I would like to clear this value. Is it possible to send “empty” value to airtable? Of course I can make something like 0 or something another. But maybe you know how to make.

  2. This value I would like to use in next screen. It will be add to client order. Maybe you know solution how this value send directly to another table?

Thank you for any suggestions.
