help needed - XML forms not displaying in my repository

Hi all

I could really do with some help here. I have a custom XML form for news articles. It works fine in the standard documents repository, but I have my iView pointing to a folder in my own CM repository.

When a user tries to directly access the "show" form, instead of the form it displays the XML code. Any ideas why this is?

My CM repository is running the following services:

layout, properties, svc_acl, tbp

EP6SP14

Thanks! Chris
