Don't know which to chose...

[SNvNothing]

I'm trying to put a 15% gold bonus and a 10% science bonus on my leader but i don't know which ModifierType to choose?
I've tried some but they all make an error when launching the game.

MODIFIER_ALL_CITIES_ADJUST_CITY_YIELD_CHANGE

MODIFIER_ALL_CITIES_ATTACH_MODIFIER

MODIFIER_PLAYER_CITIES_ATTACH_MODIFIER

MODIFIER_PLAYER_CITIES_ADJUST_CITY_YIELD_CHANGE

MODIFIER_PLAYER_CITIES_ADJUST_CITY_YIELD_MODIFIER

I don't know which to choose and how i'm supposed to put it?
Can anyone help me on this?
This is what i have (in sql) :
