How to combine the Submit button of FormSnap with Capsule?

I’d like to combine the function of FormSnap with Capsule. First, I created a practice test using FormSnap, then I added Elixir Capsule stacks to allow users to check their answers. The FormSnap stack includes a “Submit” button that enters the answers into a MySQL database. What I’d like to be able to do is activate a Capsule toggle at the same time that the user hits the “Submit” button. You can see a test page here: ( (use PageSafe PIN 8899) You will notice the a toggle at the very bottom of the page. That is the toggle I would like to activate with the Submit button. I’m guessing there is a fairly easy way to do this but my knowledge of the code is limited. Thanks
