Good day.

I'm not a php programmer, so I need a little bit of help. I created a content type Resource with CCK field Type of access. When creating a new material, I attach the file. Open/Closed is the value of the field Type of access. I need, that the attached file is shown to all, if the value of the field Type of access is Open and hidden from unregistered users, if the value is Closed. What should I do?

Thank you.
