Add Relevance conditions
Filling a form can be a cumbersome task, especially when respondents are not always sure which fields they should fill or not. While making a form field required is one way to guide your form respondents, another way to do so is by adding skip logic to fields. Skip logic is a feature that changes what question a respondent can answer next based on how they answer the current question. Assuming the relevance function is not met, a responder won't be able to fill in a field when performing data entry directly in the ActivityInfo platform. When performing data entry through android devices and ODK collect, responders sweep from one question to another and in this case he won't see a question to which he hasn't met the relevance function. You will see in this article how to use skip logic by defining a relevance function to a field.
Please be aware that relevance functions can only be added to beta forms.
Navigate to the Form Designer
Choose the field where you want to add relevance criteria
Example of a relevance function using 2 fields
In this case, the question "Is the patient pregnant?" will only be asked if the responder answered Between 15 and 45 to the question "How old is the Patient?" and if the responder selected Female for the question "What is the sex of the patient?"
