please provide a link to your pen, with just this it is not possible to know what’s wrong
Also because if I am not wrong, that test is about the behaviour of the form when the submit button is pressed, not about the submit button itself . It may also be something else, you have not provided enough informations.
I tried to change the id from id to email, but that just set me back 4 tests instead of one. I removed one of the forms that’s not doing anything, so now I’m back at two.
