App does not sync with Google Sheets

[uospino]

My problem is that the App is not updating info into the Google Sheet.

I'm building my first App.

I started fromn a Google Sheet.
From the Google Sheets menu  I opened the AppScript.

I have an Edit accion wich allows the user tu register information on a certain row and this information should be updated into the Google Sheets.

My problem is that the App is not updating info into the Google Sheet.
