One little error is all it takes

Made one little error in transcoding my GIF reader project from GP to Snap!




What happened?

wrong precedence uhhh the deepest subtraction block is in the first slot not the second

You have/are making a gif reader project??

Yes - I made one in GP a few years ago and I'm trying to convert it to Snap!

But I've had to do it by hand and I've introduced little errors like the one above.
