I am creating a form and have inserted a drop down box with reporting agency names. Is there a way for the agency name selected to appear in the footer?
Assuming you're using a dropdown content control and not a legacy formfield:
Apply a style to the paragraph that contains the dropdown, making sure that style isn't used anywhere else in the document. If necessary, create a new custom style for this purpose.
Then insert a StyleRef field in the footer, including the name of the style in the field's code. The field will automatically update to display whatever is in the styled paragraph, including what is chosen in the dropdown.
