I fixed the problem myself.
I added the fat printed line to my source code:
<?php
$editor=new CuteEditor();
$editor->ID="Editor1";
$editor->Text="Type here";
$editor->FilesPath="Some_Directory";
$editor->AutoParseClasses=true;
$editor->Draw();
$editor=null;
//use $_POST["Editor1"]to catch the data
?>
