[Survey Creator](https://support.enrollnow.io/en/knowledge-base/survey-creator?hsLang=en) June 19, 2026 # Surveys: Adding Question Validation The **Validation** section allows you to control the values your survey will accept, ensuring data accuracy and completeness. ### **Benefits of Using Validation:** - Ensures participants fill out **required fields**. - Confirms responses are entered in the **correct format**. **Example Use Case:** - Add validation to ensure participants enter a **date** in the **Birthday** field. **NOTES:**  - **Survey questions do not include validation by default.** - You can manually **add validation** to any question as needed. By using validation, you can improve data quality and ensure participants provide accurate and complete responses. ![](https://support.enrollnow.io/hubfs/Knowledge%20Base%20Import/support.ripplescience.comhcarticle_attachments5232943770381.png) ### **Customizing Required Error Text in Surveys** You can mark important questions as **required**, ensuring participants provide responses. If a required question is left unanswered, an error message will appear. **Key Features:** - The default error message is **“Please answer the question.”** - Users can **customize** the error message to provide specific guidance. **Steps to Set Up Required Questions and Customize Error Text:** 1. **Create a Survey Question** - Open the **Toolbox** and add your question. 2. **Enable the Required Setting** - Select the question and open the **Properties** panel. - Under the **General** section, toggle **“Is Required”** to **ON**. 3. **Customize the Error Message** - Scroll down to the **Validation** section. - Locate the **“Required Error Text”** field. - Enter your preferred custom error message. By following these steps, you can ensure that required questions are answered while providing clear instructions to participants. ![](https://support.enrollnow.io/hubfs/Knowledge%20Base%20Import/support.ripplescience.comhcarticle_attachments5233013417229.png) ### **Using Validators in Surveys** Validators allow you to create **custom expressions** to verify survey responses. You can use validators to ensure that participants enter data in the correct format before submitting the survey. If a response does not meet the validation criteria, the survey will **block submission** until it is corrected. **Key Features of Validators:** ✔ Ensure data accuracy by restricting incorrect entries. ✔ Customize error messages to guide participants. ✔ Apply different validators based on question type. **Example Use Case: Height Validation** If you are collecting **height** in feet and inches, the **inches** field should not exceed **12**. A **Max Validator** can be applied to prevent participants from entering invalid values (e.g., 13 inches or more). ### **How to Add a Validator: Email Validation Example** 1. **Add a Question** - Open the **Toolbox** and add a **Single Input** question. 2. **Access the Properties Panel** - Select the question and navigate to the **Properties** panel. 3. **Apply a Validator** - Scroll down to the **Validation** section. - Click the **“+”** icon under **Validators**. - Select **“Email”** to ensure only valid email addresses are accepted. 4. **Customize the Error Message** - In the **Text** field, enter a custom error message (e.g., *“Please enter a valid email address.”*). By using validators, you can enhance **data accuracy** and prevent errors before survey submission. ![](https://support.enrollnow.io/hubfs/Knowledge%20Base%20Import/support.ripplescience.comhcarticle_attachments360092631332.png) -
