My RemoteEvent won't fire, what is the problem?

Hi there! I am making a pretty simple script, where when a player touches a part, it is put on their back and it fires a message telling a localscript that the part is "picked up." However, it doesn't seem like the two scripts recieves, or even sends any information. I don't know if this has something to do with it being a part that is in workspace or not. Anyway, here are my two scripts:

****ServerScript

local bag = script.Parent

local moneyinbag = bag.Money.Value

local event = bag:FindFirstChild("RemoteEvent")

local eventfired = false

bag.Touched:connect(function(hit)
	
	local humanoid = hit.Parent:FindFirstChild("Humanoid")
	local torso = hit.Parent:FindFirstChild("Torso")
	
	if humanoid and torso then
		local bagweld = Instance.new("Weld")
		player = hit.Parent
		
		if player then
			event:FireClient(player, "PickUp", hit)
			print("pickedup") -- this is printed after the part is touched
				
			bagweld.Name = "BagWeld"
				
			print(hit.Parent) -- shows my player
				
			bagweld.Parent = hit.Parent.Torso
			bagweld.Part0 = torso
			bagweld.Part1 = bag
			bagweld.C1 = CFrame.new(0, 0, -1)
		end
	end
end)

event.OnServerEvent:connect(function( ... )
	local tuple = { ... }
	if tuple[1] == "Throw" then
		print("works") -- this is not printed
		local bagweld = player.Torso:WaitForChild("BagWeld")
		if bagweld then
			bagweld.C1 = CFrame.new(0, 0, 1)
			bagweld:Destroy()
		end
		local force = Instance.new("BodyForce")
		force.force = Vector3.new(0, 100, 0)
		force.Parent = bag
	end
end)

****Local Script

--Scripted by SonioSony

local bag = script.Parent

local moneyinbag = bag.Money.Value

local event = bag:FindFirstChild("RemoteEvent")
local pickedup = false

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local bagscreen = game.StarterGui:WaitForChild("BagScreen")

event.OnClientEvent:connect(function( ... )
	local tuple = { ... }
	if tuple[1] == "PickUp" then
		pickedup = true
		if bagscreen then
			bagscreen.TextBox.Visible = true
		end
		player = tuple[2].Parent
		mouse = player:GetMouse()
	end
end)

mouse.Button1Down:connect(function()
	print("yes") -- to check if anything happens, didn't work
end)

mouse.KeyDown:connect(function(key)
	if key "g" and pickedup then
		event.FireServer("Throw")
		local bagweld = player.Torso:WaitForChild("BagWeld")
		if bagweld then
			bagweld:Destroy()
		end
		local force = Instance.new("BodyForce")
		force.force = Vector3.new(0, 100, 0)
		force.Parent = bag
	end
end)

I am pretty new to scripting, so I am greatful for help!
