Using custom entry forms
For most Prompt messages—that is, messages that require a response from the recipients—you can gather responses from recipients using the Question and Choices fields. In some cases, you might need to gather more specific or detailed responses. You might want to collect the responses by means of a custom form.
Note: The Send External Prompts check box might be selected for some users on the Users form. In this case, you must include a note in the body of the prompt email, instructing users to log in to this application to enter the requested data or perform the actions needed on the custom form.
