Issue with Basic VLAN's

Hi there;

I might be doing this completely wrong, but I can't seem to find an answer. I am just trying to do basic LAGs between multiple N2048P switches and trunk multiple VLANs between them up to our core router. On the individual access ports, I want to have the PVID untagged for its purpose. However, I cannot ping between two devices on the same switch on the same untagged VLAN, let along between the switches. Any advice would be greatly appreciated! 

Thanks,
