Okay, I made a mistake and had 2 programs mixed up.
What I was attempting to do was automate the screen snipping tool to be able to repeat the same snipping area over and over.
I found a better tool, it's called Movavi - Screen Capture.
I automated this with ME so the F8 key captures an area of the screen and saves it to a file.
In Movavi you can set the area of the screen you want to capture.
Thanks for all the help.
