Help with PixelSearch please

OK, So i have tried getting the PixelSearch() to work but cant seem to get it to work correctly. I am needing to scan the area in the box for a color and click on the button when that color is in the area. I have tried several different things but cant seem to get it working.

Here is a image i made to give you a better understanding of what im trying to do.

Thanks for the help,

Mike
