COUNT Function
The COUNT function tells you how many values the template user provided in the interview; it can count the number of repetitions in a repeated dialog, the number of selections in a Multi Select variable, or the number of rows in a Table variable.
The difference between COUNT and COUNTER is that COUNT counts the number of repetitions in a list, while COUNTER gives you the number (index) of the current repetition.
You can use the COUNT function with either a repeated dialog, a Multi Select variable, or a Table variable to insert appropriate language, control interview flow, or otherwise determine a template's logic.
