Hi,
The problem is that unless the Reader Extensions have been applied through LC Reader Extensions ES2, then data connections do not work in Reader.
A summary of the main features that are available/restricted depending on what the user has (Acrobat/Reader), whether the form is Reader Enabled, and how the form was Reader Enabled:

Can you hard wire the data into the form?
Hope that helps,
Niall
