I'm setting up a membership form for a fitness facility. At the end of the form, I would like a checkbox that says: "I have read and agree to xx's Terms & Conditions". I understand how to add a checkbox, but I'm not sure how to include a PDF that opens in a pop up when someone clicks on Terms & Conditions (or whatever best practice is used with Gravity Forms).
I'm new to Gravity Forms and I'm not a developer, so if you could please be as specific with your response as possible it would be greatly appreciated.
