Expected 'then' when parsing if statement, got '=' help me?

game.Players.PlayerAdded:Connect(function(plr)


local sd = math.random()

if sd = 0 then
	print("NotHaoBorn")
	
	if sd = 1 then
		print("HaoBorn")
	end
end
	
	
end))`

When writing if statements, you're required to have two '=' signs.

So, all you need to do is

game.Players.PlayerAdded:Connect(function()
	local sd = math.random()
	if sd == 0 then
		print("NotHaoBorn")
		if sd == 1 then
			print("sd is 1")
		end
	end
end)

Let me know if you have any questions.

In an if statement, putting "==" will check if sd is 0. if you put "~=", it will check if sd is not 0. If you just put an equals sign, it will not work.
