Nm_atualiza with message "Output"

Hello guys,
My objective was to have an autosave on a record used to write meeting notes.
As I read in the forum, I have included in the event Onscriptinit the following code:

?>

It is nice but my problem is that after it saves, I get a popup with “Output” next to the close button of the popup.
IHow can.I get rid of this “Output” message ? Or can I replace it by “Auto save completed” for example ?

Thanks !

Yannick
