Hi superbowl50chicago bears,
Do you mean that you have a PDF form and you want to be able to see what fields needs to be filled out? If that's the case, when you have the form open in either Reader or Acrobat, you'll see a button in the upper-right corner that says "Highlight Existing Fields." Press that button, and the fields that need to be filled out are highlighted.
Please let me know if that answers your question.
Best,
Sara
