How do I add a custom variable in my survey?
Using custom variables allows you to include information about a respondent in the survey without making the respondent answer those questions. In other words, it helps avoid asking for information that you already know. For example, imagine that there's a question in the survey that asks for the respondent's email. If you remove the
email question from the survey but still need the respondent's email address, you can add a custom variable, and the email address will also show up in the survey reports. By extension, if you already know your respondents you can use custom variables and
piping to auto-fill questions on your survey.
To add a custom variable in your survey:
- Click Advanced Options on the upper-right side of the survey builder.
- Click Custom Variables.
- Complete the URL Parameter box. Make sure you remember what you write in this field, because you'll need to use exactly the same variable name in the URL when sending out your survey.
- Enter a description for the custom variable in the Label box.
- Select the type of variable you'd like to use from the Type dropdown list:
- Text
- Email
- Number
- Choice: In the Options box, type in the choices (one per line). At least two options are required to save the variable.
- Click Save Variable.
