I have managed to make one work - sort of - but my problem in getting a button that triggers it. The first pic shows what it looks like in Site Designer, the second what it looks like on the website (the button no longer exists!) and lastly, the pop up that happens when I click on that very faint Contact Me on the website
yep similar when using a reveal to hold the form using S-Drive
looks terrible and not a good visual experience for users
looks great when hosted with my hosting service
