title: Identifier not found on compiler (Free Pascal)
body: <p>I'm trying to change the color of a panel on Lazarus on mouse hover.</p>
  
  <p>I try run this code on Lazarus: </p>
  
  <pre><code>unit test;
  
  {$mode objfpc}{$H+}
  
  interface
  
  uses
  [...]
  
  type
  
    { Tvendas_menu }
  
    Tvendas_menu = class(TForm)
  
      [...]
      procedure StartMouseEnter(Sender: TObject);
      [...]
  
  
    private
      { private declarations }
    public
      { public declarations }
    end;
  
  var
  [...]
  
  implementation
  [...]
  
  procedure Tvendas_menu.StartMouseEnter(Sender: TObject);
  begin
     Start.Color := $00E7E7E7;
  end;
  [...]
  </code></pre>
  
  <p>But when compiling the program show the following error code:</p>
  
  <p>Error: Identifier not found "Start"</p>
  
  <p>I'm sure that "Start" is the name of the panel on Object Inspector and .lfm file.</p>
  
  <p>I try to change "Start" to another name but the error still occurs.</p>
  
  <p>Thanks!</p>
