My INPUT() doesn't save changes

[Jujuy_Adventure]

Hello Community, how are you?
Today I ask for your help because I ran into a problem when trying to store a value in a field using INPUT().
As I was telling you, I have created an action that sets the values ​​of some columns. Using the Input() function I have created a popup requesting some of these values. But when I try to save the changes nothing happens.
I don't get a field validation error and it doesn't save the set value either. The only thing I can do is CANCEL the change.
What can be caused this?
