Re: "template container" declaration error

I am trying to declare "containerr" class for the template, so
that it would contain explicit size for the templated object:
MyClass.hpp
#include <queue>
template <typename T>
// Container class
class Element
{
public:
        Element( T t, int size)
        {
                m_t = t;
                m_size = size;
        }
        virtual ~Element() {};
        T m_t;
        int m_size;
} ;
// Queue wrapper
template <typename T>
class MyQueue
...
//STL queue declaration:
std::queue <Element> m_queue;
....
I have the following error: "ISO C++ forbids declaration of
`m_queue' with no type,
  expected a type, got `Element'"
Why doesn't compiler see declaration of type 'Element' ?
