translation problem

Hi,

This function doesn’t work. Is there any update fro translation?

add_filter( ‘prso_gform_pluploader_i18n_script’, ‘plupload_i18n’ );
function plupload_i18n( $i18n_filename ) {

//Use fr,js file – remove .js from filename
$i18n_filename = ‘he’;

return i18n_filename;
}

Thank you.
Svetlana
