how do i return values?

hello, i am new to returning and i need some help with it. i am currently making an AI and i need some help with returning two variables, the target humanoid and the target humanoid root part. i want these two values to be returned to a new function but it says the value i am trying to access is unknown, this probably means it is a problem with scope, which i am also not very good at.

local animatronic = script.Parent
local animatronicHumanoidRootPart = animatronic:FindFirstChild("HumanoidRootPart")
local animatronicHumanoid = animatronic:FindFirstChild("Humanoid")

local function findTarget()
	print(1)
	for i, players in pairs (game.Players:GetPlayers()) do
		local targetCharacter = players.Character or players.CharacterAdded:Wait()
		if targetCharacter then
			local targetHumanoidRootPart = targetCharacter:FindFirstChild("HumanoidRootPart")
			local targetHumanoid = targetCharacter:FindFirstChild("Humanoid")
			if targetHumanoidRootPart then
				if targetHumanoid then
					if (targetHumanoidRootPart.Position - animatronicHumanoidRootPart.Position). magnitude < 100 and targetHumanoid.Health > 0 then
						return targetHumanoid, targetHumanoidRootPart -- returning the values. im not sure how to return multiple values, i assume this is how you do it though
						
					end
				end
			end
		end
	end
end

local function noTarget()
	findTarget() -- the value function thats returning the values
	
end

local function followTarget()
	local targetHumanoid = findTarget(targetHumanoid) -- accessing the variables gives me the unknown error, im only trying to access one at the moment
end

while wait(5) do
	
end
