How can I make every question required in order to proceed to the next?

The current form we use is great, but sometimes clients don't answer all of the questions, and we'd like them to at least attempt.  How can we make each question required?

I've just looked into your form and found that "Required" option is on for every field.

So, nobody can submit the form leaviing any of the fields blank.

I've also cloned your form and have tried to submit the form skipping any of the fields but failed to submit.

That means your form is working just fine as you want it to be if I understand your query correctly.

Please let us know whether this answer satisfies your question.

Thank You.
