Saving Input Text When Selecting a Repeating Group Cell

Hello,

I’m building a page where a list is created on the left side using a repeating group, and the right half of the screen updates when a cell is selected. I want to be able to select a cell, enter text in the text input on the right side, and then press a save button to store it.

I’ve put a lot of effort into it, but after pressing the save button, if I click on a different cell and then return, the text I had entered disappears.

Could anyone please advise on how to retain the entered data even when switching screens using the repeating group cells?

Thank you in advance.

Is your data a list of text? And are you adding to that list instead of replacing the first input words?

No, the data is a single text data.
I attach the picture of my problem.
Even if I save text data, the text isn’t kept in there after I click the other cell.
