Thank you for your post.
When you insert a file as a reference, the complete file path is stored. Since the file path is on a server, make sure each person has that server mounted on their computer so they can access the file.
I was thinking of simply making a hyperlink like on a website to the folder beside the containers for reference. It is the hyperlink to a folder on the server is what I am having trouble with. And it seems like the simplist thing.
