Acceptance error message not appearing if not accepted

I’ve been reading forum posts for hours and all the people that are experiencing the same thing seem to have been using an older version of the plugin, so the advice they were given is likely to be obsolete. Maybe not though… I don’t know. I’m hoping someone can help.

It’s pretty simple really… there’s an acceptance checkbox that, if unchecked, disables the submit button (great) but doesn’t tell the user why they can’t click submit.

I need an error message (the one I set in the messages section) to appear like any other required field validation message does.

I’m also redirecting the form once it’s submitted sucessfully… maybe that’s the problem? This is what’s in my “additional options” textarea:

on_sent_ok: “location = ‘http://rosendarpinobasketball.com/events/basketball-skills-camp/’;”
acceptance_as_validation: on

Does it all have to be on one line? Or is there some character that needs to separate the two?
