Amitoj,
A page error can indicate a couple of things here. I am assuming you are directly referencing the external data property for the HTML field.
- The external data file referenced does not exist
- The HTML control cannot display the type of file referenced.
Also, please make sure your HTML control | Domain List | Contains is set to Prohibited Domains
This radio button section controls how Agentry interprets the Domains list below which is empty by default. Since you are using it to view external data files you will want it set to Prohibited Domains so the control tries to view all attachments.
