Reselect, Crop and save Button

I would like a button that reselects part of an image, crops it and saves it with the same name with one click. I tried to make one with this, Reselect, Crop & Save It did reselect the part I selected from the first image, but that is all. Thanks much.

The command in that post should have been on multiple lines; it should look like this:

Show VIEWERCMD=reselect
Show VIEWERCMD=save,quiet
Clipboard COPYNAMES=unc

As always I'm grateful and I'll never regret my purchase of Opus.
