In your survey's Look and Feel settings, you have the option of automatically numbering all of the input fields. When enabled, this will apply to all field types except Text Blocks, Line Separators, Spacers, and Page Breaks. As you add, remove, and reorder fields, they will automatically be renumbered accordingly.
To display field numbers:
- While editing your survey, click on the Survey Options tab.
- Click on the Look and Feel panel to expand it.
- Under Survey Style, select the Display Field Numbers checkbox.
- Click the Save Changes button.
