First App, need to make field editable

[PixelRothko]

Heyo,

so I've deployed my first, simple AppSheet app for mobile use and ran into an issue.

Basically, I need to make one of the number fields editable via app, so that users could input a number and it updates in the google sheets and as a result updates the entire table.

I've made this field 'editable' in the 'columns' view of the Data section, but when I press this field in the app, it goes to an edit mode, but the field there is greyed out, not clickable and is stuck on 0.0.

How do I fix it? 

Thank you.
