Support Forums : Error message

I created a survey with several pages. After answering the questions on the first page and going to the next page, an error message appears that no answers have been filled in on the second page yet. So this is the first thing one sees one page 2, without even starting to answer the questions.

It is the same text that would appear if one wants to go from page 2 to 3 without filling in the questions on page 2, just that the questions are not coloured yellow which are empty. How can I solve that the error message does not occur when changing pages?

Thanks for your help!
