Float has no field getY?

I was working on a 2d platform game, and then after I ironed out some bugs that crash it now I can't open it at all. It just loads the error screen saying "Float has no field get Y" I don't really know what it means and its randomly calling some of my code errors even though they were fine earlier. It doesn't seem to affect my most recent scene which is fitted with a new scene behaviour I made.  Maybe I should replace the scene events with that?

Do you see any errors in the logs?

Some of the "GetY" things are gone now,  there's only two left, one shows an error at the top of the event, while the other seems to show just the scene. I looked at the logs and they seem to show a lot of code marked with (ERR).

Please can you post them here.
