How do you make it so when a player on a team dies the total score of the other team goes up?

player = game.Players.LocalPlayer
_G.Rangers_score=0
_G.Moondarkers_score=0
game.StarterGui.ScreenGui["Team score"].TextLabelMOONDARKERS.Text=("Moondarkers:").._G.Moondarkers_score
game.StarterGui.ScreenGui["Team score"].TextLabelRANGERS.Text=("Rangers:").._G.Rangers_score

while true do 
	wait (0.2)
	if player.Humanoid.Health <=0 and player.TeamColor==BrickColor.new("Storm blue") then
		_G.Rangers_score=_G.Rangers_score+1
	end

game.StarterGui.ScreenGui["Team score"].TextLabelMOONDARKERS.Text=("Moondarkers:").._G.Moondarkers_score
game.StarterGui.ScreenGui["Team score"].TextLabelRANGERS.Text=("Rangers:").._G.Rangers_score
end
print(_G.Rangers_score)

Why not put,

Player Died (Player)
if player.TeamColor==BrickColor.new("Storm blue") then
 _G.Rangers_score=_G.Rangers_score+1
else if Player.TeamColor== BrickColor.new("THE OTHER TEAMCOLOR HERE") then
_G.OTHER TEAM HERE_score = _G.OTHER TEAM HERE_score

Hopefully you know this isn't the full one. You'll have to script it yourself but I told you how to script it.

player = game.Players.LocalPlayer _G.Rangers_score=0 _G.Moondarkers_score=0 game.StarterGui.ScreenGui["Team score"].TextLabelMOONDARKERS.Text=("Moondarkers:").._G.Moondarkers_score game.StarterGui.ScreenGui["Team score"].TextLabelRANGERS.Text=("Rangers:").._G.Rangers_score

while true do wait (0.2) if player.Humanoid.Health <=0 and player.TeamColor==BrickColor.new("Storm blue") then _G.Rangers_score=_G.Rangers_score+1 end

game.StarterGui.ScreenGui["Team score"].TextLabelMOONDARKERS.Text=("Moondarkers:").._G.Moondarkers_score game.StarterGui.ScreenGui["Team score"].TextLabelRANGERS.Text=("Rangers:").._G.Rangers_score end print(_G.Rangers_score)
