From the prototype I'd guess this.

template<class T>
void Stack<T>::Output(T element)
{
  cout<< element;
}

I don't understand why you have a parameter. It seems you want to output the whole stack.

template<class T>
void Stack<T>::Output()
{
  for ( int i = 0; i < pool.size(); ++i ) {
    cout<< pool[i] <<endl;
  }
}

My compiler is complaining about the call to the function Output as in Output (dStack); saying that Output is undeclared ?

Right. You prototype Output to take a T and try to pass a Stack<T>. I guess you'd call it like this for the two different functions I wrote.

// Output takes a T parameter
dStack.Output( dStack.top() );

// Output takes no parameters
dStack.Output();

Hamrick i'm still getting compiler errors.
Could you copy the code into a compiler to see what it does or is that too much to ask?
I would just love to see what the problem was ?
Thanks for all your inputs thus far.

I compiled it and everything's like I said. Change how you create Output then change how you call it. I also added a body for push so that it runs, I hope you don't mind.
