When creating rule stages, you'll first want to make sure that Fountain has a record of the question/answer field you'd like to use for the rule.
For example, let's say I added a new question to my position form:
To create a rule stage using this question, I'll need to submit a test position form answering the question:
Once the position form comes into Fountain with the new question/test response, I can select the question as a field to create a rule stage:
Please note that this also applies to Typeform and Wufoo, so if you've added a new question to your form and wish to use it for a rule stage, you'll need to send in a test application form in order to see the question in the dropdown.
