what does it mean by character Upvalue nil value?
local Tool = script.Parent
local activated = false
local player = game.Players.LocalPlayer
local character = player.Character
Tool.Activated:Connect(function()
if activated == false then
activated = true
local Humanoid = character:FindFirstChild('Humanoid')
Humanoid.Health = 100
end
end)
This keeps on giving me an error : 18:06:37.585 - Players.soccerdeadmatchteam.Backpack.med kit.LocalScript:9: attempt to index upvalue 'character' (a nil value)

Upvalues
An upvalue is an external local variable; a local variable declared outside of a function body. Here is an example
```lua local var = "abc";
local function fn() --// var is an upvalue here! since it is not declared in this scope end ```
Your issue
The issue with your script is that it ran before the character was even loaded.
The common practice to wait for the character is player.CharacterAdded:Wait()
lua
local character = player.Character or player.CharacterAdded:Wait();
Pretty much if the character already is loaded then it will not need to wait. If it is nil it will wait for the character. And then character variable is assigned to the character model.
