This is on a client site running EE 2.6.1 and Freeform 4.0.12.
I have a Freeform-based contact form with dynamic recipients in place and working based on user's section of 10 different checkboxes. So far so good.
Now the client is asking that the return page URL be dictated by those same checkboxes - so they can track different things in Google Analytics.
What they want isn't just a 1:1 mapping of checkbox to URL - they want some different combinations (if user selects a & b, do this, if they select all checkboxes do that, etc).
I see Freeform Pro has a return field that allows different return URLs based on the field selection, but what I need is to leverage the existing checkboxes, and be able to insert different logic statements before the final return URL is chosen.
