Thanks, yes, that's the issue, you have assigned the "Steve Perry's Web Sharpen" action to the open document event in the Script Events Manager.
Do you really wish to automatically sharpen every file you open???
The open document doesn't meeet the requirements of the action, thus the error.
Without seeing the action steps, I can't comment on why the file structure doesn't match the action steps, at a guess, it's most probably a layer naming issue.
