The ‘Contains’ formula is used to check if a particular option was selected in a checkbox question type. In CMS (platform v1), the way to do that is to write something like this: [checkboxq(value)] == 1. This has been changed up in V2. The new formula to check if a checkbox contains a specific value is:
containsContains([questionName], 2)
This formula excepts two parameters:
The variable/question name
The value to check
Examples:
containsContains([CheckboxQ1], 3)
The formula will get the last response(s) for the question “CheckboxQ1” and check if '3' was one of them.
