Are you sure you picked the button that said "My Own"? If you did
that, you would be able to run it on your own picture.
And, like I said, you may need to tweak the thresholds.
Why don't you post your image somewhere, such as at http://drop.io??????????????????
That's because it's always so much better to give image processing
advice when you can actually see an image.

Sorry I don't have a Facebook account so I can't see your image. Can
you post it to http://drop.io - it's really, really easy. Just make
up some name, like "kenny" for your drop, then specify your photo for
uploading, then tell us the URL (e.g. https://drop.io/kenny).

By the way, your error message didn't make sense. Something got
corrupted when you copied the error message. Are you sure you joined
any lines broken by the newsreader? Do you have any red syntax errors
on the right hand side? Can you set a breakpoint? (You won't be able
to if you have a syntax error).

Like I said, you need to do this in hsv space NOT rgb space. But if
those thresholds work for you then just replace the low and high
thresholds in my demo code and it should work. If it doesn't, then
those thresholds are no good (hence my suggestion to use hsv space),
or else you did something wrong. How do you know it's no good?
