Can I have a response set that is not editable by the user?

You cannot have a response set that is not editable by the user.  However, you can use field scripting to create a template in which the user makes a selection, and then based on that selection, other fields on the template are populated.  The user would not be able to edit these fields.  You would need a field on the master pdf for the dropdown list where the user makes a selection and one for each of the fields that need to be populated based on that selection. The fields would be set up like this:

Field one - contains the dropdown selection

• Field type tab - text coming from user entry
• Format tab - Field usage should be set to "Hide Field"
• Data capture tab - User control type = dropdown list
  • The List options would look like this:
    • A|A
    • B|B
  • The initial A and B would need to be replaced by the options you would like the user to see/select.

Field two - contains the text that needs to populate the field based on the selection in field one

• Field type tab - text coming from static text or field scripting
• Field Scripting tab - Set the script type to be VB.  The script would look like this:
  Choose(FieldOne, "A|Phone number for location A|B|Phone number for Location B", "")
• You would replace FieldOne with the name of the field containing the dropdownlist.
• You would replace Phone number for location A and Phone number for location B with the actual text you want to populate the field.
