Titan hook for delete_transient

[askaria]

Hello!
I need delete_transient after updating the page in the admin panel, but for some reason the hook does not work.

$titan = TitanFramework::getInstance( 'fairy' );

My function:

function fcook_cat_delete_transients($container, $activeTab, $options) {
if ( $activeTab == 'homepage-options' ) {
delete_transient( 'some_old_transient' );
}
}
add_action( 'tf_pre_save_admin_fairy', 'fcook_cat_delete_transients', 10, 3 );​

Gives an error:
PHP Parse error: syntax error, unexpected end of file in....
