The only mistake I found in your code is in the lower left corner - the Greyscale constant isn't connected to anything.
I don't know if this could be causing the crash though. How do you know that it crashes? Have you changed any other parts of the project? (ie robot main?)
Also I'm not sure if you've noticed, but this is last year's example code. It should still work, but I don't want you to waste your time on something that you're not going to use
Oh, and by the way, please don't attach pictures by putting them in .docx files in the future. You can upload the picture itself, or even the actual .vi
