Blocky script doesn't do what I want Topic is solved

[HoogendoornJH]

I want to turn on a fan when the CO2 level in a room is above 750 ppm and turn it off when the CO2 level is below 725 ppm. However, at temperatures above 25°C under no circumstances the fan should be switched on when the outside temperature is above the inside temperature.

For this I made the attached Blocky script. However, it doesn't work. It did work without the condition that the fan should not be turned on at temperatures above 25°C when the outside temperature is above the inside temperature.

Now, is the script wrong or is Blocky unable to handle the nested If statements?

In the script it is:
Buiten Temp/Humi (Davis) = outside temperature;
Binnen Temp/Hum (Davis) = inside temperature;
CO2 Woonkamer = CO2 level in the room;
Switch Suskast Werkkamer = Switch fan.

Hoi HoogendoornJH,

I think you chose the wrong "if" function.
2x * is not possible.
