Certificate project

How to submit our project of building a form.There is no such option

You should first Run the Tests (by button on the left size of the screen, or by pressing Ctrl + Enter) and then Submit and go to next challenge (button on pop-up window, or by pressing Ctrl+Enter one more time).

Yeah but this screen will not pop out if your code does not pass the test.
So, you have to make sure your code passes all the tests (everything).
