Class template, my first attempt

Im getting linker errors when trying to create a class template. I can't seem to see what is bad with this code. Any help would be great, thanks.

in main.cpp:

Code:

// main.cpp : practice.

#include <iostream>
using namespace std;

#include "Stack.h"

/***********/
/* Globals */
/***********/

/**************/
/* Prototypes */
/**************/

/************/
/* Internal */
/************/

// Our primary routine.  This is called when the program starts.
//
// Return:	We always return 0.
int main(void)
{

	CStack<int> values;

	int num = 4;


	if (values.isEmpty())
		cout << "Values is empty..\n";
	else
		cout << "Values has an item in it..\n";

	num = 5;
	cout << "Adding 5 to CStack values...\n";
	values.push_back(num);

	num = 3;
	cout << "Adding 3 to CStack values...\n";
	values.push_back(num);

	cout << "Taking one out.\n";
	values.pop(num);
	cout << num << "Removed..\n";
	
}

in Stack.h

Code:

#pragma once

template <typename Type>
class CStack
{
private:
	static const int MAX = 10;
	Type items[MAX];
	int top;
public:
	CStack(void);
	bool isFull(void) const;
	bool isEmpty(void) const;
	bool push_back(const Type & item);
	bool pop(Type & item);
};

in Stack.cpp

Code:

#include "Stack.h"

template <typename Type>
CStack<Type>::CStack(void)
{
	top = 0;
}

template <typename Type>
bool CStack<Type>::isFull(void) const
{
	return top == MAX;
}

template <typename Type>
bool CStack<Type>::isEmpty(void) const
{
	return top == 0;
}

template <typename Type>
bool CStack<Type>::push_back(const Type & item)
{
	if (top < max)
	{	
		items[top++] = item;
		return true;
	}
	else
		return false;
}

template <typename Type>
bool CStack<Type>::pop(Type & item)
{
	if (top > 0)
	{
		item = items[--top];
		return true;
	}
	else
		return false;
}

There are plenty of threads about this problem on this forum.
Short Answer:
Put the code from Stack.cpp into Stack.h and delete Stack.cpp.
