Struggling to post value to GUI (SOLVED)

Questions
#1

Hello its again, i’m trying to post the value for my players health into the GUI script but i keep getting “nil” returned whenever i try to do anything with that value. I had an issue with the message recipient but i think thats ok now. I’ve tried changing the value thats being sent to just a regular integer and got an error saying “table expected, number received”.
This is the player script:

function on_message(self, message_id, message, sender)
	if message_id == hash("trigger_response") then
		print("collide")
	-- checks if enemy and player collide
		if message.enter then
		-- only damage player when entering enemy radius
			take_damage(self, 5)
			msg.post("health bar", "health_update", {new_health = self.health})
			-- send current health value to gui
		end
	end
end

This is the gui script:

local function update_health(self, health) 
	print(health)
end

function on_message(self, message_id, message, sender)
	-- check if health message recieved
	if message_id == hash("health_update") then
		-- pass new health into update health
		update_health(message.new_health)
	end
end

You forgot to pass self to the update_health function.

and in on_message you call:

update_health(message.new_health)
