Changing the status/textlabel?

Hi, I was making this script where when you touched this part it would damage you for 5 seconds and it would change the text on the textlabel to say status: poison. But my script wont change the text. Can you help?

Textlabel script:

local plr = Game.Players.LocalPlayer
repeat wait() until plr
local status = Instance.new("StringValue",plr)
status.Name = "status-"..plr.UserId
repeat wait() until plr:WaitForChild("status")
while true do
    wait()
    script.Parent.Text = "Effects: "..plr.status.Value
end

Brick touched script:

local no = false
local plr = Game.Players.LocalPlayer
repeat wait() until plr
script.Parent.Touched:connect(function(part)
if not no then
no = true	
local humanoid = part.Parent:FindFirstChild("Humanoid")
if (humanoid ~= nil) then
plr.status.Value = "Poison"
for time = 5,0,-1 do
humanoid.Health = humanoid.Health - 5
wait(1)
end
wait(2)
no = false
end
end
end)

Can you try to help me with my script?

Hope you don't mind if I re-write your scripts but here you go:

TextLable LocalScript:

local plr = Game.Players.LocalPlayer
status=plr:WaitForChild("status")
status.Changed:connnect(function()
    script.Parent.Text = "Effects: "..plr.status.Value
end)

Extra Player Added Script:

game.Players.PlayerAdded:connect(function(player)
	stat=Instance.new("StringValue", player)
	stat.Name="status"
end)

BrickTouched Script:

derp=false
script.Parent.Touched:connect(function(part)
	if derp==false then
		hum=part.Parent:FindFirstChild("Humanoid")
		if hum then
			plr=game.Players:GetPlayerFromCharacter(part.Parent)
			if plr then
				derp=true
				status=plr:FindFirstChld("status")
				if status then
					status.Value="Poisoned"
				else
					print("Status not found, creating one")
					status=Instance.new("StringValue", plr)
					status.Name="status"
					status.Value="Poisoned"
				end
			for time = 5,0,-1 do
				hum.Health = hum.Health - 5
				wait(1)
			end
			wait(2)
			derp=false
		end
	end
end)

That should do it, you made a good attempt but there were several things wrong and some not needed parts. You can't access a LocalPlayer from a regular script and there is no point on putting a .Touched local script in a brick that can be touched by anyone. I made a PlayerAdded script because server scripts can't mess with things that are made by clients if you have FilteringEnabled. Just in case that didn't work, the .Touched event would put a status in the player if one was not found. A .Changed even is more efficient in this situation as it runs if a property has changed, not in a while loop which takes up processing power. A :WaitForChild() function will wait for a child, it doesn't need to have a repeat wait() until. I hope this helped.
