Program from C++ Primer not compiling?

[Immo]

I really have no idea what the problem is as Visual Studio doesn't find a problem with any of the code. I've been trying to read along and get the program that they're using to run but it's not building. What's causing this?

* EDIT: Figured it out. The error wasn't detected by VS, but it was due to the same constructor definition being used - also incorrectly, at that.

Screen.h

#ifndef SCREEN_H
#define SCREEN_H

#include <iostream>
#include <string>
#include <vector>
using std::string;

class Screen
{
public:
	typedef string::size_type pos;
private:
	pos cursor = 0;
	pos height = 0;
	pos width = 0;
	string contents = "";

	void do_display(std::ostream &os) const { os << contents; }
public:
	Screen() = default;
	Screen(pos ht, pos wd, char c) : height(ht), width(wd), contents(ht * wd, c) {}
	Screen(pos ht, pos wd, char s) : height(ht), width(wd) { char s = ' '; contents(ht * wd, s) }
	char get() const { return contents[cursor]; }
	inline char get(pos ht, pos wd) const;
	Screen &move(pos r, pos c);
	Screen &set(char);
	Screen &set(pos, pos, char);
	Screen &display(std::ostream &os) { do_display(os); return *this; }
	const Screen &display(std::ostream &os) const { do_display(os); return *this; }
};

#endif

inline Screen &Screen::move(pos r, pos c)

	pos row = r * width;
	cursor = row + c;
	return *this;
}

	pos row = r * width;
	return contents[row + c];

Source.cpp

	myScreen.move(4, 0).set('#').display(std::cout);
	std::cout << std::endl;
