RemoteFunction not firing server?

I know this question has been asked a lot. This really stumped me.

--client
local function connectClasses() --to play button
	for _,v in pairs(menuclass:GetChildren()) do
		wait()
		if v:IsA('TextButton') then 
			if v.Name ~= 'Back' then 
				local inf = tinfo(.5,Enum.EasingStyle.Elastic)
				spawn(function()
					v.Button.MouseButton1Click:connect(function()
						--print('clickitied')
						spawn(function()
							ClassSelected:InvokeServer(plr,v.Name)
						end)
						local goal = {}
						goal.Position = menuout
						local t0 = twn(menuclass,inf,goal)
						t0.Completed:wait()
						gbls.Debris:AddItem(startmenu,0)
						spawned = true
						main.Enabled = true
						cam.CameraType = Enum.CameraType.Custom
					end)
				end)
			end
		end		
	end
end

--server
data.Combine("DATA","gold","sh_coins","class")

spawn(function()
	glbs.Plrs.PlayerAdded:connect(function(Plr)
		
		local goldstore = data("gold",Plr)
		local shcoinstore = data("sh_coins",Plr)
		local classstore = data("class",Plr)
		
		function callRemote(remote,value)
			sendDataToClient:InvokeClient(Plr,remote,value)
		end
		
		callRemote('Gold',goldstore:Get(500))
		callRemote('Stronghold Coins',shcoinstore:Get(0))
		callRemote('Class',classstore:Get('None'))
		
		goldstore:OnUpdate(callRemote)
		shcoinstore:OnUpdate(callRemote)
		classstore:OnUpdate(callRemote)
		
	end)
end)

classSelected.OnServerInvoke = function(Plr,Class)
	callRemote('Class',Class)
	return print('class remote called')
end

Any help is appreciated. I don't have any loops before any of this code.
