Ok this is driving me crazy. All I'm looking to do is create a "drop box" library. Where someone can upload a document, select the type of document and then it will automatically be redirected into the relevant library.
This is my workflow (one part of it, I stripped it down in an attempt to diagnose the error):

Can anyone spot why it might not be working? When I had several of these lined up it brought up an error saying "make sure columns and their settings are the same in each list" - which I have done. Then when I broke it down just to this one step it says completed but without having carried out any of the stages.
Please help!
