Receiving a compilation error for the _location variable with the same finished code.

namespace TreehouseDefense { class Tower { private const int _range = 1; private const int _power = 1;

private readonly MapLocation _loacation;

public Tower(MapLocation location)
{
  _location = location;
}

public void FireOnInvaders(Invader[] invaders)
{

  foreach(Invader invader in invaders)
  {
    if(invader.IsActive && _location.InRangeOf(invader.Location, _range))
    {
        invader.DecreaseHealth(_power);
        break;
    }

  }

}

}

Tower.cs(12,7): error CS0103: The name `_location' does not exist in the current context.

It's just a spelling error. The variable is being defined with the name "_loacation" (with an extra "a").
