How do I rename files sequentially in automator based on a variable? I'd like to rename some image files. Is there a way to have the service ask what number to start at? 



Everything here is set up as I'd like it to be. Though, when I run the script, I would like the service to ask me for a variable and then input it into the "start numbers at" box.

Is there a way to do this? Thanks.
Checked "Show this action when the workflow runs". 

This allows me to choose what number to start at.
