This script is not changing the colour of Wood parts?

Hi, I'm implementing a system where you can customize the colour of your gun. The RecolourValue is a BrickColorValue. It prints "1" and also prints "2", but does not print "3".

PrimaryMaterial = "Wood"

for i,v in pairs(script.Parent:GetChildren()) do
	
	print '1'	
	
	if v.ClassName == "Part" or v.ClassName == "WedgePart" then
		
		print '2'		
		
		if v.Material == (PrimaryMaterial) then		
			
			print '3'			
			
			v.BrickColor = BrickColor.new(script.Parent.Parent.Parent.shopandinventoryvalues.RecolourValue.Value)		
			
		end		
	
	end
	
end

Thanks for your help!
