How do I populate screen elements with values from a data master?
1. Login screen with username & password. On page unload I save the username in a variable
2. In the second screen I need to populate, on page load, labels and text inputs with info from data master, specific to that username.
Each row contains the username, which can be used as selection criteria.
What's unclear to me is how I set label xyz content to be the value of cell first_name for ex from the data master.
