That fresh snapshot is much better!

So there's currently only one version of "DistanceTo", and it takes 2 arguments. But you're calling it in MapLocation.cs with just one. Now it could be that you're in the middle of some changes and the course is about to have you make another version of "DistanceTo" that will work with the one argument.

But in case that's not it, or if you just want to make it compile anyway, you can convert the MapLocation object into separate X and Y values like this:

            return DistanceTo(location.X, location.Y) <= range;

That's the same workspace I looked at for you last Thursday, where it turned out there was a stray semicolon, remember? You said you removed the semicolon and it worked.

Are you having a different issue now? You'll need to make a fresh snapshot and post the link to that one.

That's still the same link to the old snapshot. A snapshot "freezes" the state of your workspace at the moment you make it. To show your current issue, you'll need to make a fresh snapshot and share that new link.
