Member function redeclaration not allowed

So, below is code for a binary tree, the structure is referred to as TreeNode. I'm having some trouble separating what information goes into the TreeNode.h file and the TreeNode.cpp file.

Here is the .h file

#pragma once
#ifndef TREENODE_H
#define TREENODE_H
#include <iostream>
#include <string>
class TreeNode{
private:
std::string word;
int count;
TreeNode *left;
TreeNode *right;

TreeNode() {}

public:
	TreeNode(std::string word, int count, TreeNode *left, TreeNode *right);
	void downtree(std::string s);
	void printTree();


};
#endif

Here is the .cpp file

#include <stdafx.h>
#include "TreeNode.h"
#include <iostream>
using namespace std;



TreeNode::TreeNode(std::string word, int count, TreeNode *left, TreeNode *right);
{
	downtree(word);
}
void TreeNode::downtree(std::string s){	
	if (word.compare(s)  > 0 ){
		if (left == NULL) {

		left = new TreeNode;
		left->word = s;
		left->count = 1;
		left->left = NULL;
		left->right = NULL;
		}
		else	
		{left.downtree(s);
		}
	}
	else if (word.compare(s)  < 0 ){
		if (right == NULL) {

		right = new TreeNode;
		right->word = s;
		right->count = 1;
		right->left = NULL;
		right->right = NULL;
		}
		else{
		right.downtree(s);
		}
	}
	else if (word.compare(s)  == 0 ){
		count++;
	}
}

The intent of this tree is to be able to take in a string and place it in the proper position.

The error messages:
Error 5 error C2761: '{ctor}' : member function redeclaration not allowed
Error 6 error C2447: '{' : missing function header (old-style formal list?)
Error 7 error C2228: left of '.downtree' must have class/struct/union
Error 8 error C2228: left of '.downtree' must have class/struct/union

Does anyone know the source of these error messages? I need a second pair of eyes on this. Thanks!

You have a ; at the end of line 8

Aha, thank-you!
