Help to add a new event

[Istaego]

Hi everyone,
I am writing here to ask for help to introduce a new event. I would like it to be renewed every year. The idea is to produce two versions, for each country: in the first, when less than 40% of the poor population cannot afford the living needs, I would like the maximum taxation to be reduced by 20%, the imput of factory reduced by 10% and the output increased by 5%. In the second, when more than 60% of the poor population can afford the needs of life, I would like the opposite to happen. The maximum tax increased by 20%, the factory input increased by 10% and the output reduced by 5%.
I don't have the skills and the time to learn how to set up this event. I've tried to do something, which you can read below, but I think it's a failure. I thank any good man in advance for their help. Forgive me for the English, I know it's not that great.

This is my failed attempt:

# negative trade balance
country_event = {
id = 50480
title = "Negative trade balance"
desc = "You have a negative trade balance. To reach an equilibrium, we have to raise taxes"
picture = "Bankruptcy"

Trigger = {
year = 1836
civilized = yes
NOT { poor_strata_life_needs = 4 }
}
mean_time_to_happen = {
months = 12
modifier = {
factor = 10000 }
}

option = {
name = "It had to happen"
max_tariff = -0.20
factory_input = -0.10
factory_output = +0.05 }
}

#solve a -possible- positive balance
country_event = {
id = 50487
title = "Positive trade balance"
desc = "You have a positive trade balance. To reach an equilibrium, we have to lower taxes"
picture = "Bankruptcy"

trigger = {
year = 1836
civilized = yes
poor_strata_life_needs = 6
}
mean_time_to_happen = {
months = 12
modifier = {
factor = 10000 }
}

option = {
name = "It had to happen"
max_tariff = 0.20
factory_input = 0.10
factory_output = -0.05 }
}
