The code is here:

ACTION depositnlock::modsettings(uint32_t sp, uint32_t m){
   check( has_auth( get_self() ), "Provide permission to set stake percetage");
   /*
   auto the_settings = _settings_instance.get_or_create( get_self(), defaultsets );
   /*
       the_settings.stake_percentage = sp;
       the_settings.minimum_stake_time = m;
       _settings_instance.set( the_settings, get_self() );
   */
}

I cleaned up your question because it was unreadable. Please learn how to properly ask and format questions here.

The code you posted is still so badly formatted that it says the code for reading/creating and setting the singleton is commented and therefore neither compiled nor executed but I didn't want to change the whole text.

By interpreting the error message you posted it looks to me like your defaultsets is invalid but that's uncertain. Please post more - and correctly formatted code so that we can help.
