How to adjust this Automator file?

[Max McCarty]

Hi,
You created this automator file that sharpens the image and then sets the auto lighting to 50%. I want to create an automator file that just does the sharpening. I tried removing the auto lighting part, but that didn't work. Can you please help me? Thanks!
