C3861 Error (I really tried)

I promise I searched high and low for the solution. You're my last resort.

I am getting the error

Error 6 error C3861: 'saveSessionLurch': identifier not found 420 1 cs482newUI

Here is my code for XMLExport.h

#ifndef XMLEXPORT_H_
#define XMLEXPORT_H_

#include <vcclr.h>
#include <string>

using namespace std;

    class XMLExport{
    public:
        void saveSessionLurch();
        XMLExport();

    };//end class XMLExport

#endif

this is my code for XMLExport.cpp:

#include "StdAfx.h"
#include "XMLExport.h"

void XMLExport::saveSessionLurch(){

}//end SaveSessionLurch

this will eventually do something but I am just trying to get it to compile as of right now.

and here is the code for Form1.h. I actually cut out most of the code that isnt relevant to this question.

this is the top of the code:

#pragma once
#include "Cell.h"
#include "Session.h"
#include "systemObjectWrapper.h"
#include "XMLExport.h"

and this is where the error occurs. The SaveFileDialog opens up so I know the click is working:

private: System::Void saveSessionButton_Click(System::Object^ sender,System::EventArgs^ e){
                      SaveFile开发者_如何学运维Dialog^ saveFileDialog1 = gcnew SaveFileDialog;
                      saveFileDialog1->ShowDialog()
                     saveSessionLurch();//THIS IS WHERE THE ERROR IS

               }

Thank you very much in advance for your help. It will be well rewarded

You need to call saveSessionLurch on an instance of the XMLExport class.
