Skip logic rules allow you to determine whether a field should be shown or skipped based on the value of a previous field. 


Skip logic rules can be set for all field types (including groups) and are useful when you would like to skip a field or group that should not be answered by a participant based on a previous response they gave. For example, if a participant indicates that they are male, all fields/groups relating to pregnancy should be skipped for this participant.


You can add, remove or edit skip logic rules at any time.


An icon on the right of the field name indicates whether skip logic has been added to this field (green) or not (grey). Clicking on this icon takes you to the relevant tab so that you can add, view or edit your skip logic rules. 





Setting up skip rules for a field/group:


Click on the field or group you want to add skip logic to. In the 'Skip logic' tab, click on 'Configure skip logic' (only if you haven't specified any skip logic rules yet).




Choose whether the field should be 'skipped if' or 'shown only if' certain conditions are met (3). Indicate whether this skip rule should apply only when all the prerequisites are met, or if any one of the prerequisites is met (4). 


Next, select the source field (5) - the response to the source field will determine whether the current field should be shown/skipped. Different comparison operators (6) will be available to choose from, depending on the type of the selected source field. Finally, enter a value (7) for the condition. Depending on the source field type, this can be a static value, field reference or a function




In the example above, the field 'first_name' will be skipped if the field 'consent' is equal to 'No' or if the value of the 'age' field is less than '18'. 


Below is a summary of field types that can be used as source fields and the comparison operators and values that can be selected/chosen in each case.


Source field typeComparison operatorValue of condition

static value, field reference or function
Single select
Equal to, not equal to, has a value, has no value

Multiple select

Calculated valueEqual to, not equal to, greater than, less than, less than or equal to, greater than or equal to, has a value, has no value
static value, field reference or function



You can add as many skip logic rules to a field as required. You can also easily remove a skip logic rule by selecting the bin icon to the right of it, or remove all skip logic rules by clicking 'Remove all'.




Hint: Test your skip logic rules by using the 'Previewbutton on the far right in your top toolbar.  






Note: It is not currently possible to branch from one field to another. You can either add a skip rule to each individual field, or you can group fields together and then add a skip rule to the group.
