Textboxs are disabled when using code

I’m working on this page:
https://www.wixmeup.com/one-time-deal-test5

When the user enter to slide 3 in the slideshow the textboxs are disabled (can’t enter texts).
I don’t why it’s happening. Sometimes it’s working and sometimes not.

Anyone have an idea why?

Hi Oren,
It’s a bug on our end. We’re working on it and it will be resolved soon.

Ok.Thanks.
Can i get a notification here when it does?
