Hello,
I would like to show a calculation of a number that the user has put in on one of my screens. It did it like so:

After that screen, they would see their value (like a price) and if they are unsatisfied with that, I would like for them to have an option to change the previous answer and have it calculated again. This is what I did:


When I tested this, the calculation worked for the first time but when the option to change their initial value is chosen, the resulting value is 0. Can anyone help with this?
