Using TEXTJOIN in a Dynamic Table

TEXTJOIN combines multiple selections into a single line of text separated by commas. When a table allows more than one choice, TEXTJOIN gathers all selected options and groups them together so the form can understand and respond to those selections. This helps apply rules, or trigger actions based on your answers. You don’t need to do anything special—just complete the form normally, and TEXTJOIN works automatically to make sure the form behaves correctly based on what you choose.
