Allow the end-user of your app to "look up" a row of data in the app's data source (learn more on how to add a database as a data source to your app). This is what the row selector question looks like from the end-user's perspective when running the app:
From any Question Page, click 'questions' and then choose row selector. After you add this question to a page, you must connect it to a data source and specify which column from that database you want to allow the end-user to search through:
Like all other questions, the row selector defines a variable. Give this variable a semantic name. This variable represents the selected row from your database, so a good name for this variable could be "selected_X" (e.g. selected_client).
As soon as you finish setting up your row selector question, you will have access to variables for each column in your database table. These new variables are labeled using the row selector variable + column name:
You can use these new variables for anything you can use a normal variable for, such as creating document templates.
