Why the valor isnt part of workspace when it is created?

I done a script when a player touch a block if he is in a determined team, the team will add a +1 to TeamA or B but when I touch the block it doesnt work. What can be the trouble?

local TeamA = Instance.new("NumberValue")
TeamA.Name = ("TeamA")
TeamA.Value = 0
TeamA.Parent = workspace

local TeamB = Instance.new("NumberValue")
TeamB.Name = ("TeamB")
TeamB.Value = 0
TeamB.Parent = workspace

script.Parent.Touched:connect(function(hit) --Get what made the hit.
    --Define player's variable here with the method GetPlayerFromCharacter!
    local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
    script.Parent.BrickColor = Player.TeamColor
    wait(.2) 
 
if Player.team == game.Teams.TeamA
	then
	game.Workspace.TeamA = game.workspace.TeamA.Value + 1
	Player.leaderboard.Painted.Value = Player.leaderboard.Painted.Value + 1
end

if Player.team == game.Teams.TeamB
	then
	game.workspace.TeamB = game.workspace.TeamB.Value + 1
	Player.leaderboard.Painted.Value = Player.leaderboard.Painted.Value + 1
	end
    

end)

I know what's going on.

A thing I learned recently: When there's a .Touched event, the LocalScript / Script NEEDS to be putted in the StarterGui. Other thing, I don't really like using NumberValues, I would recommend you using IntValues. Having said that, here's what you want:

local TeamA = Instance.new("IntValue") --Change to IntValue.
TeamA.Name = "TeamA" --Remove the ()
TeamA.Value = 0
TeamA.Parent = game.Workspace --Make sure he knows what's workspace.

local TeamB = Instance.new("IntValue") --Change to IntValue.
TeamB.Name = "TeamB" --Remove the ()
TeamB.Value = 0
TeamB.Parent = game.Workspace --Make sure he knows what's workspace.

script.Parent.Touched:connect(function(hit) --Get what made the hit.
    --Define player's variable here with the method GetPlayerFromCharacter!
    --local Player = game.Players:GetPlayerFromCharacter(hit.Parent): This works, but there's another way I prefer.

	local Character = hit.Parent.Name
	local Player = game.Players[Character]

	if hit.Parent:FindFirstChild("Humanoid") then --Check if it's a player.
    		script.Parent.BrickColor = Player.TeamColor --In here you're saying Brick's Color should be the Player's TeamColor. I think what you want is the opposite. I didn't change that, but if what you want is CHANGE THE PLAYER'S TEAMCOLOR *TO* THE BRICK'S COLOR, then swap the variables there up.
    		wait(.2)
	end

	if Player.Team == game.Teams.TeamA then
    		game.Workspace.TeamA = game.Workspace.TeamA.Value + 1
    		Player.leaderboard.Painted.Value = Player.leaderboard.Painted.Value + 1 --leaderboard? try like this, but if it won't work, switch 'leaderboard' with 'leaderstats'.

	elseif Player.Team == game.Teams.TeamB then
    		game.Workspace.TeamB = game.Workspace.TeamB.Value + 1
    		Player.leaderboard.Painted.Value = Player.leaderboard.Painted.Value + 1 --leaderboard? try like this, but if it won't work, switch 'leaderboard' with 'leaderstats'.
	end
end)

After 2 hours, here's your script there up ^^

If this solves your problem, please mark as the solution.

As always, good scripting!
