Hi, i want 4 boxes for full name form. how can this be added?

i've tried making prefix as first name but it does not seems to work for all other fields

please check my form and see what's wrong with it.

I did check your form and found that you have enabled "Prefix" as textbox in the full name field which seems to work as expected in your form. Please check the screenshot below:

I would suggest you to please let us know the problem you are having and we will take a look.

We will wait for your response.
