multiple editors in php

hi!
my php code is like this

$sBasePath = "/admin/";
$oFCKeditor = new FCKeditor( 'n_label' ) ;
$oFCKeditor->BasePath = $sBasePath ;
$oFCKeditor->Value = $row['n_label'];
$oFCKeditor->Create() ;

$sBasePath = "/admin/";
$oFCKeditor = new FCKeditor( 'n_content' ) ;
$oFCKeditor->BasePath = $sBasePath ;
$oFCKeditor->Value = $row['n_content'];
$oFCKeditor->Create() ;

when i save it (i have no submit buton i saving it from toolbar) only first editor (n_label) updating database.
for n_content won't update database. so where is the problem? Any help will be nice thanks guys...
