Wildgrowth with ava/sd rune

[Makkann]

init start
	local WildGrowth = 2130 -- id of rush wood
	local shootPosx = $posx -- This is east 
	local shootPosy = $posy+1 -- This is north
init end 

auto(200)
if topitem(shootPosx, shootPosy, $posz).id ~= WildGrowth and itemcount("wild growth rune") > 0 then
setsetting('Persistent/Scripts/Runeshooter/Enabled', 'no') 
	useitemon("Wild Growth Rune", 0, ground(shootPosx, shootPosy, $posz))
	wait(300,500)
else
setsetting('Persistent/Scripts/Runeshooter/Enabled', 'yes')
end

Will this work? The idea is to stop use avalanche rune if the item south from you isn't a wildgrowth
