Hi JingChi,

You need to replace this line in your code :

return (pathStep < _path.Length) ? _path(pathStep) : null;

with following :

return (pathStep < _path.Length) ? _path[pathStep] : null;

If you see carefully, _path is an array of type MapLocation, so we need to use square brackets in the ternary expression, and not parenthesis. In your case you use, _path(pathStep) which makes the compiler think that it is a function call.

Let me know if you have any further questions. All the best!
