We received a batch of intake [forms] with missing contact phone numbers and inconsistent account [ids]. I need a realistic diagnosis: is the [template] unclear, are certain [clerks] skipping fields, or is the intake flow forcing omissions? Tell me the one analytic check to run on this batch that proves the root cause and the immediate fix I should push to the floor.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

FAQ

about this task
  1. Open your PDF in Acrobat.
  2. Go to 'All tools' > 'Prepare a form'.
  3. Click the 'Add a text field' icon in the toolbar.
  4. Draw the box where you want the text field to be.
  5. Double-click the new field to set its properties, like its name and tooltip.

A Tooltip is a short description for a form field. It matters because it helps people who use screen readers understand what information they need to put in that field. Without a Tooltip, a screen reader user might not know what the field is for, making your form hard to use for everyone.

Yes, when you use 'Prepare a form' with a scanned PDF, Acrobat will try to automatically find and add form fields. However, it might not find all of them, or it might make mistakes. Always check the fields it adds and manually add any missing ones.

You should avoid Word's form tools because they often do not export to accessible PDF fields correctly. This means the form fields might not work well in Acrobat, or they might not be usable by people with disabilities. It's best to create your document in Word and then use Acrobat's 'Prepare a form' tool to add the actual form fields.

  1. After you finish making your form in Acrobat, go to 'File'.
  2. Choose 'Save as Other'.
  3. Then select 'Reader Extended PDF'.
  4. Click 'Enable More Tools (includes form fill-in & save changes)'.
  5. This will create a special version of your PDF that Reader users can fill out and save.
