If mouse hovers then kill player not working but no error?

I'm tryna make it so if you have over a brick with a name it kills the player but the script doesn't do anything.

-- Local script

local players = game:GetService("Players")
local player = players.LocalPlayer
local mouse = player:GetMouse()
local rs = game:GetService("ReplicatedStorage")
local char = player.Character


local event = rs:WaitForChild("Killplayer")



if mouse.Target.Name == "Ivan" then
	event:FireServer(player,char)
end


while wait() do
	print(mouse.Target)
end

-- Server script

local players = game:GetService("Players")
local rs = game:GetService("ReplicatedStorage")
local event = rs:WaitForChild("Killplayer")



event.OnServerEvent:connect(function(player,char)
	
	print(char:GetChildren())
	
	local human = char:FindFirstChild("Humanoid")

	
	if human then
		human:TakeDamage(5)
	end
end)
