Why i cant just press check my answer button?

Question

When i write code (not in playground) i cant just even press check button, keyboard appears its impossible to click

Answer 1

On the “fill in the blanks” sections, you can’t check the answers if the fields aren’t filled out and in many cases if you don’t use the right number of letters. If the correct answer is 6 letters long, you only put 5 letters because you are incorrect, it won’t let you test your answers. That’s a clue that you have a wrong answer.
