For some reason the output of this code says plr is not a valid member of Players???

-- the variable plr should get the players name but for some reason says plr isnt a valid member idk whats wrong :/

a= script.Parent
whatever = game.Workspace
player = script.Parent.Parent.player.Value
wait(1)
while true do
	if whatever.Game.scored.Value == true then
		if a.Value ~= "" then
			plr = a.Value
			if game.Players.plr.TeamColor == game.Players.player.TeamColor then
				game.Players.plr.scored.Value = game.Players.plr.scored.Value + 1
			end
		end
	else
		wait()
	end
end

The script thinks that you are locating an object called plr. To fix this all you have to do is put brackets around the variable like this: [plr]

The dot must go after the brackets not before.

Your script should look a little like this:

a= script.Parent
whatever = game.Workspace
player = script.Parent.Parent.player.Value
wait(1)
while true do
    if whatever.Game.scored.Value == true then
        if a.Value ~= "" then
            plr = a.Value
            if game.Players[plr].TeamColor == game.Players[player].TeamColor then
                game.Players[plr].scored.Value = game.Players[plr].scored.Value + 1
            end
        end
    else
        wait()
    end
end
