Can't fire client with a remote event?

Ok Let Me Explain What You Did Wrong Ok :)

Client Script:

local Repstorage = game:service("ReplicatedStorage") -- Gets Replicated Storage
local Event = Repstorage:WaitForChild("StartTimer") -- Use :WaitForChild() Because If The Event Has Not Been Replicated Yet Then It Wont Error
Event.OnClientEvent:Connect(function() -- Runs The Function Every Time The Event Is Fired
	print("hi") -- Prints Hi
end) -- End Of Fucntion

Server Script:

local Repstorage = game:service("ReplicatedStorage") -- Gets Replicated Storage
local Event = repstorage:WaitForChild("StartTimer") -- Use :WaitForChild() Because If The Event Has Not Been Replicated Yet Then It Wont Error
local Part = script.Parent -- The Part
Part.Touched:Connect(function(Hit) -- Hit Event
	local Player -- A Variable
	if Hit.Parent:IsA("Model") then -- Check
		Player = Hit.Parent -- Model Found
	end -- End
	if Hit.Parent.Parent:IsA("Model") then -- Check
		Player = Hit.Parent.Parent -- Model Found
	end -- End
	if Player then -- Check
	else -- Otherwise
		return -- Return
	end -- End
	if game:service("Players"):FindFirstChild(Player.Name) then -- Check
		Player = game:service("Players"):FindFirstChild(Player.Name) -- Change Variable
	else -- Otherwise
		return -- Return
	end -- End
	Event:FireClient(Player) -- Fire To The Player
end) -- End Hit Function

Edit: Forgot The Server Side.

Edit 2: Forgot To Explain Server Code.
