title: ISSI Inno Setup function
body: <p>Im using <strong>ISSI plugin</strong> for Inno Setup and i am getting a error trying to use a ISSI function in my [CODE] section </p>
  
  <pre><code>Uknown identifier 'ISSI_CurPageChanged'   
  </code></pre>
  
  <p>The plugin is free and it´s main functions are available at:
  <a href="http://members.home.nl/albartus/inno/ISSI_Functions/ISSI_Functions_Overview.htm" rel="nofollow">http://members.home.nl/albartus/inno/ISSI_Functions/ISSI_Functions_Overview.htm</a></p>

  <p>I have to use this ISSI function because otherwise i get a duplicate error trying to use CurPageChanged.</p>
  
  <p>My code is the follow:</p>
  
  <pre><code>#define ISSI_WizardBitmapImage2 "EcraFinal.bmp"
  #define ISSI_WizardBitmapImage2_x 495
  #define ISSI_WizardBitmapImage2_Align
  
  #define ISSI_UseMyCurPageChanged
  #define ISSI_BeveledLabel ""
  
  #define ISSI_WizardBitmapImage "EcraInicial.bmp"
  #define ISSI_WizardBitmapImage_x 495
  #define ISSI_WizardBitmapImage_Align
  
  ; Include Plugin ISSI 
  #define ISSI_IncludePath "C:\ISSI"
  #include ISSI_IncludePath+"\_issi.isi"
  
  [Setup]
  ...
  
  [Run]
  ...
  
  [Code]
  procedure ISSI_CurPageChanged(CurPageID: Integer);
  
  begin
  if CurPageID = wpWelcome then 
  begin
  WizardForm.NextButton.Caption := SetupMessage(msgButtonInstall);  
  //or := 'YourNewNextButtonText' or := ExpandConstant('{cm:YourCmTitleForNext}')
  WizardForm.CancelButton.Caption := ExpandConstant('{cm:Cancelar isto}');
  end; //begin + end to make changes only for this single page
  end;
  [/Code]
  </code></pre>
  
  <p>The _issi-isi file exists and is being correctly addressed by my app. 
  Any sugestions for what it might be? Thank you in advance.</p>
