At any stage within the survey, you can ask your customers provide a free text response to a question.
Select "Comment Question" from the drop down box and click "+Add"
We recommend limiting to using this only once within your survey to avoid too much free text for your staff to review and interpret.
If you selected the "Modern" survey design, you also have the option to add a unique background for this question.
To do so, click on the checkbox next to "Apply unique background for this question", then click on the box "Click to upload" and select the file from your computer/file location.
