If I understand what you are saying you have an MFC application that is a dialog; that's fairly standard. Within the dialog are a few controls, one of which is an edit box. You then say, "A right click on the edit box produced a drop down and "Add variable" was selected.". That part I don't understand, an edit box is just that, a box that you type text into which allows simple editing. What I would expect to happen would be that you would type something into the edit box, and then click the button. Your button handler would be something like:
void Cvs_2008_get_port_numberDlg::OnBnClickedButton1()
{
    UINT port_number;
    BOOL status;
    int  last_error = 0;
 
    port_number = GetDlgItemInt( IDC_EDIT1, &status );
    if (status == FALSE)
        last_error = GetLastError(); 
// ...
// store the port number somewhere

When you prefix your call to GetDlgItemInt with m_box_get_port_number (the edit box variable name) you are trying to find the item IDC_EDIT1 within the edit control. But the edit control does not have a child window with that ID so the call fails.
