Answer validation allows you to set rules on your questions to ensure your respondents provide answers within some criteria that you have set. For example, you might want to set a word limit for a Multi line question.
Answer validation can be used for Choice (multiple answers), Single line, Multi line and Grid questions.

To add answer validation to your question:
- In the Build area, click on the question you want to add answer validation to.
- Open the question’s Properties by clicking the Cog button.
