Please don't post screenshots of broken workflows. Upload the workflow somewhere and post a link to it instead.
It's very difficult to tell how something is broken unless the problem is very, very obvious. See this thread.
However, there is one very obvious problem with your workflow: The trash executable is in /usr/local/bin and that isn't on PATH when you're running code in Alfred.
Change trash ~/Downloads/* to /usr/local/bin/trash ~/Downloads/*
