Copying multiple field boxes to one single field box as a read only
I am setting up a form that has a comments section. The comments section consist of multiple boxes (font size and font set) to ensure the text doesn't change so that it stays over the lines in form design. I want to take the entire text from all box fields and copy to one individual box on a separate page. I am sure this will require script of some sort, can anyone help me to do this?
