Multi pages not working in demo

Hi guys,

I was trying to setup a test form on your demo site, and was unable to get the multiple pages working?
I would create for example two required text fields (Name, Surname), then a page break (ticking “check required fields” for both Next and Previous), then add an Address textarea field, and a submit button.
When viewing the form, I could click on “Next” without filling in any fields, and then the Previous button doesn’t work, and no warnings about required fields.
This is a bit of a blocker for me, if I could get the multipage forms to work, I’d be very interested in using/purchasing your plugin.

Thanks
