c++ - Is it legal to call a base class's template function in a child class?

“Undefined reference to” template class constructor

I've just started using templates, and I was wandering whether or not it is actually legal to call a template function in a child class. My problem is with the Template function ChangeSprite in the code below. It is being called in a child class, but this creates a linking error. If I remove the template part, and just give it one of the multiple things I plan on using it with instead it works fine, so I'm fearing that I won't be able to do this.

//base class
#pragma once  

#include "Tile.h"
#include 
#include "Sprite.h"
#include "WindowCreater.h"
#include "Directx.h"  
#define LeftClickParameters WindowCreator *gw, Mouse* mouse
struct Grid
{

    SPRITE *sprite;

    int width, hieght;
    int w, h;
    int x, y;
    Grid(int width, int hieght,SPRITE *sprites);
    list tilew;
    list> tileh;

    //methods

    void savefile();

    void openfile();
    virtual void MoveLeft() = 0;
    virtual void MoveRight() = 0;
    virtual void MoveUp() = 0;
    virtual void MoveDown() = 0;
    virtual void addrow() = 0;
    virtual void deleterow() = 0;
    virtual void addcolumb() = 0;
    virtual void deletecolumb() = 0;


    //template functions
    template  void ChangeSprite(SPRITE *newSprite,list tilew,list> tileh);

    // Virtual methods
    virtual list ReadTiles() = 0;
};    

and this is where it is being called

 //how the function is being called
 void Map::Brush(SPRITE *newSprite, POINT MousePosition)
 {
  Grid::ChangeSprite(newSprite,mapTilew,mapTileh);
 }
