Hello!
I'm practicing for the 2nd Core Exam. One of the tasks mentioned "See help Files for secret settings".
I got the formula correct, but was curious for future assistance how to use the files for the secret settings. See the hint in the workflow below as example.
@jjimenez this is most likely pointing you to the Help function within the tool's configuration panel which would take you to the Alteryx Help page for a specific tool, in your case the formula tool. Its an excellent resource to help you understand the possibilities of the tool.
