NIPO ODIN Version 5.17
Surveys started from a URL
When a survey is started from a URL published on a website, stratification can only be used if an empty Sample table is created for the survey. For each contact a new (empty) sample record is created in the Sample table. Use the *SAMPLEDATA or *ADDRESS command in the NIPO ODIN questionnaire to fill database fields and the *STRAT command to check your stratification cells and then jump to a specific question.
By default, stratification is impossible without a Sample table.
