Linker Error, please help

Hey guys, I'm getting some kind of linker error. Any help would be appreciated.

Here is what I have..

Header File:

           #ifndef _LinkedSortedList_
            #define _LinkedSortedList_

            #include "LinkedNode.h"

            template <class Elm> 
            class LinkedSortedList : public SortedList<Elm>
            {
            public:

                LinkedSortedList();
                ~LinkedSortedList();
                void clear();
                bool insert(Elm newValue);
                bool getfirst(Elm &returnValue);
                void print() const;
                bool find(Elm searchValue) const;
                int size() const;

            private:

            };

I'm using visual studio btw

Thanks!

I found a solution. The linker error can be fixed a few ways. One way is by including the implementation file in the main.cpp file.
Another way is to create a SortedLinkedList object in the implementation file.
