Little help with ai modding

[Tormentor]

I need some help with ai scripting. I read the Ai Files Modifiers.txt guide but there's something i don't understand.
I wrote this in FRA_Poland.ai (It's just a test)

garrison = {	
	province_priorities = {
		102  = -1   #Sedan
		96  = -1   #Longwy
}
         area_multiplier = {
		102  = 0   #Sedan
		96  = 0   #Longwy
	}
}

But when GER declare war against the Allies, France puts 9 divisions in Sedan and Longwy.

Province_priorities is set to -1... and area_multiplier to 0. In the Ai Files Modifiers.txt i read "If an area contains a specific province, multiply the basic need by value " This means that if Sedan needs 9 divisions in order to defend this province from enemy attacks, it will be multiplied by 0. So it should be 0 and I shouldn't see any division there. Am i wrong? Did I miss something? Can you tell me what should I write so that french ai doesn't deploy any divisions in Sedan and Longwy?

There's probably an AI file switch that overwrites your settings.

mmh i don't think so =\

the FRA_Poland.ai file is loaded in this ai event

################
# Poland Invasion AI
#############################################
event = {
	id = 3002001
	random = no 
	country = FRA
	
	trigger = {
		ai = yes
		event = 2003036 # Danzig or War AI
		war = { country = POL country = GER }
	}

	name = "AI_EVENT"
	style = 0	
	
	date = { day = 1 month = september year = 1939 }

	action_a = {
		command = { type = ai which = "switch/FRA_Poland.ai" }
		command = { type = ai which = "Air_Strategic.ai" }

and the FRA_Poland.ai is

I think I didn't understand correctly how area_multiplier works... I'll make more tests...
