Need help with this linker error... please

What I am trying to do:
I have a problem -- but I suppose you might have guessed that.
I am trying to write a tree of arbitrary data. The idea behind it is:
for the programmer using it -- most likely me -- will be able to store any data type in the tree and access it through a key. The tree will dynamically sort all the data according to the value of the key. This tree consists of two classes the main class called "cNode" and the class called "cTree". Why did I separate them into two classes I don't know but I am sure I had a good reason for that. I declared each class in it's own header and defined the methods if the corresponding "*.cpp" file the problem is during linking.

What is happening:
When linking I get the following errors:

LinkLists error LNK2019: unresolved external symbol "public: __thiscall Tree::cTree<unsigned int>::cTree<unsigned int>(void)" (??0?$cTree@I@Tree@@QAE@XZ) referenced in function _main

LinkLists error LNK2019: unresolved external symbol "public: void __thiscall Tree::cTree<unsigned int>::Add(int,unsigned int)" (?Add@?$cTree@I@Tree@@QAEXHI@Z) referenced in function _main

I know the have been defined because I wrote them in the *.cpp
I have done this with other programs. I am curious as to what is happening here. I figured I missed something.

Here are the usual specs...

Sorry I just got tired of doing syntax highlighting
Any help you can offer will be appreciated ... thanks in advance

Use 'php' tags:

PHP Code:

---

/****************main.cpp**************************  **/
#include <iostream>
#include "Tree.h"

using namespace std;
using namespace Tree;

int main(int argv, char* argc[])
{
    cTree<unsigned int> *tree = new cTree<unsigned int>();
    tree->Add(25,0x4455);
    tree->Add(20,0xFFCC);
    tree->Add(23,0xD05C);
    return 0;
}

Template implementations must be accessible to the compiler, so they need to be in header files.

> Use 'php' tags:
Actually, don't.

Well... that sucks I guess I'll just have to write everything in the header then Thanx for your help....actually maybe I'll try something else. Thanks for the help TTFN!
