A newby needs help

Is there any way to trace or display field values during or after previewing a page?

How do you pass a field value from a display page to a to a dynamic page.
I am displaying a series of title fields in a table. The user clicks on the desired title field, I output it to a text field to verify and next I link to another page but the selected title field is not correct in the new page.

try “console.log”. It´s your friend.
