Hello everyone,
What I am trying to do I have found several part solutions and suspect the answer is staring me in the face. Below is the closest I have got and there are some very complex alternatives I have tried to no avail.
I have two libraries; one an input stage for which Members can upload folders and edit columns and and one an output stage for which members can only view and download. In both there is a folder to be uploaded and some data columns to complete.
Whatever goes into the input stage I will lock at some point so Members can no longer edit or upload (i.e the view will be removed for them) and they can see the additional information that can be added by Owners in the output stage.
So far I have been able to copy files with from one libary to another but I also want the column contents to be copied when they are updated. Also, if a file is deleted from the input stage I want that to be deleted in the output stage as well. Bascially, whatever happens in the input stage library I want relfected in the output stage library.

The input stage looks like this:

and the output stage currently looks like this

Note that the Capture.jpg was deleted from the input stage but remains in the output stage. I have noticed that while it copies individual files it does not copy folders, which would also be required.
I hope that explains things reasonably clearly. First time user so apologies in advance. I'm wondering if I need mutiple triggers and mutiple actions.
