Selecting a row from a repeater and then copying the data the suer selected and adding it to the previous page

Hi everyone, I am quite new to Axure and I am struggling with how select a row from a repeater and then copying the data the user selected and adding it to the previous page. I am trying to develop a flight app and this is at the booking menu, when the user clicks on location text flied and a new page open with all the location (built as a repeater) I am having difficulties to select the row of the repeater and then copy only 1 column of that onto the previous page in the text field.

I would be grateful for any help if possible.

Thanks so much in advance.
