Urgent help required

I have included below the class declarations and the struct I am using in my program.

I am getting the following 3 error msg's:

Cannot convert 'int' to 'Word' in functions BSTree<Word>::isEmpty() const
Cannot convert 'char*' to 'Word' in function List::readList()
Type mismatch in parameter 'data' in call to 'BSTree<Word>::insertData(const Word&)' in function List::readList()

Can someone pls help me with this because I am totally lost

Code:

template <class T>
class BTNode
{
   friend class BSTree<T>;

   private:
	BTNode (){left=right=NULL;}
	BTNode (const T& el){info = el; left=right=NULL;}
	T info;
	BTNode<T> *left;
	BTNode<T> *right;
};

Code:

template <class T>
class BSTree
{
    friend class List;

    public:
	BSTree (){root=NULL;};
	BSTree (const BSTree<T>& rhs); 
	BSTree<T>& operator= (const BSTree<T>& rhs);
	~BSTree (){clear(root);}

	T isEmpty () const {return root==NULL;}
	void insertData (const T& data);

       private:
	BTNode<T> *root;
	void clear (BTNode<T> *treeRoot);
	BTNode<T> *copyTree (BTNode<T> *treeRoot);
	void insertHelper (BTNode<T> *&treeRoot, const T& 
data);
	void printInOrder (BTNode<T> *treeRoot);
	int countNodes (BTNode<T> *treeRoot);
};

Code:

const int MAX=20;

struct Word
{
    char wrd[MAX];

};

Code:

class List
{
  public:
         void readList ();

  private:
         Word x;  //struct obj
};

//==============================
void Dict::readList ()
{
    BSTree<Word> tmp;  //BSTree has type struct

    ifstream infile;
    infile.open ("wrdlist.txt");

    infile >> x.wrd;

    tmp.insertData (x.wrd);
    infile.close();
}

I answered a tree question the other day, but haven't really got time for yours at the moment. Just go through checking all your references and pointers, thi si a likely cause of "cannot convert" type errors

I cant find the problem....pls pls someone help me

> T isEmpty () const {return root==NULL;}

root==NULL is a conditional expression, but your return type is T (Word). Maybe make the return type bool:
bool isEmpty () const {return root==NULL;}

> tmp.insertData (x.wrd);
Should be:
tmp.insertData (wrd);

Since wrd.x is of type char *, not of type Word.
