why isnt this player script working? NOT ANSWERED

You forgot to add BrickColor.new before your brickcolor

wait()

function FR()
if game.Players.LocalPlayer.TeamColor == BrickColor.new ("Bright red") then
    script.Parent.Text = game.Teams.Atlas.Score
end

FR()
game.Teams.Atlas.Changed:connect(FR)

1. Why is there wait? You don't need one in this case.
2. Why are you calling a function and then letting an event call the function?
3. TeamColor is a BrickColor
4. The Score script... Look up leaderboard in the wiki...

Wait

The wait is for when you are doing a PlayerAdded type event in a local script. You can't do player added in a local script. You can reach the player through LocalPlayer, but the script runs before the player joins. So that's why the wait is there.

FR

Why are you calling the function and then calling it again with an event? Why are you using a Changed event? You can see if a player died using the Died event.

workspace.Player.Humanoid.Died:connect()
    print("A person died!")
end)

we can see who killed a player by using tags.

workspace.Player.Humanoid.Died:connect()
    if workspace.Player.Humanoid:FindFirstChild("Tag") then
        print("Player was Killed by "..workspace.Player.Humanoid.Tag.Value.Name.."!")
    else
        print("A person died!")
    end
end)

To insert a tag, make an object value. The value of the object value will be the player who is trying to kill the other player.

--This script will be in a sword or something.
function tag(humanoid)
    if not humanoid:FindFirstChild("tag") then
        local tag = Instance.new("ObjectValue", humanoid)
        tag.Name = "tag"
        tag.Value = game:GetService("Players"):GetPlayerFromCharacter(script.Parent.Parent.Parent)
        wait(2)
        tag:Destroy()
    end
end

script.Parent.Touched:connect(function(char)
    if char:FindFirstChild("Humanoid") then
        tag(char.Humanoid)
    end
end)

TeamColor is a BrickColor

A TeamColor is a BrickColor! So instead of TeamColor == ("Bright red") try

if game:GetService("Players").LocalPlayer.TeamColor == BrickColor.new("Bright red") then
end

Look here.

Here is a better version of your script. This isn't the whole thing, I'm just making the script work.

--Local Script
function FR()
    if game.Players.LocalPlayer.TeamColor == BrickColor.new("Bright red") then
        game.Teams.Atlas.Score = game.Teams.Atlas.Score+1
        script.Parent.Text = game.Teams.Atlas.Score
    end --close the if statement with an end.
end

game.Players.LocalPlayer.Character.Humanoid.Died:connect(FR)

Hope this helps!
