Open file in a View with related fields

Hello,

When I try to open an attached file in a view with related fields show the next message "You are not authorised to access this file in Zoho Creator. Go to Home"

Let me explain better:

Form1
N.Client
Field1
Field2
Upload file

Form2
Lookup (N.Client Form1)
Field2
Field3

The view is based on form2 showing fields of form1 (related fields).

How can I do this?

Many Thanks

Xavi
