?attempt to call a nil value while trying to make an executor for a script builder

Hello! I'm trying to make a project without loadstring but instead the loadstring module. It just keeps erroring on line 3, for "attempt to call a nil value":

script.Parent.RemoteEvent.OnServerEvent:Connect(function(dummyvalue,a)
	loadstring=require(script.Loadstring)
	loadstring(a)()
end)	

Thanks!
