Data didn't displayed after user input

Hi, Chua here, want to ask why the data input by users can’t show in the text box that I created to show the users’ value such as Full Name, Phone Number, etc. I’ve added these fields in the data type already

For the input, I used input, no brainer, for the display of data, even though it match the fields of data that I want to show, but it can’t display out once I refresh it.

Also to ask how to add a “Save” function in my app for user profile page, thx guys!
