Survey Source Code
Choose one of the options below to use source code in your surveys.
Use variables in a URL: Insert a link to your survey to define special variables and generate a source code when clicked. See Define source code with special variables in links.
Enter values for a survey: Enter default source and subsource code values while editing a survey.
The difference between the two methods is that the first option creates a link on the survey, and the source code is set when a constituent clicks the link. In the second option, the default source code is set when a constituent clicks the Submit button on a survey.
