Hello community,

can anybody help me with this?

Every question have Display name which is:

  1. What is your favorite food? (question1)
    etc....

Could you help me how to show friendly name when the field is required?

EDIT: It may help others - I have made all titles of the fields hidden due to some styling in H1, so the internal Name of the field is "question1". The title would be in Display Name "What is your favorite food?". But I deleted all the text from the Title, so the Designer is using internal Name of the column:

When the text is present, you can see it in validation.

I may be looking now for a script that will hide all the Titles from the Designer and keep the Text Box to be filled.

Thank you
Regards
