Simulate core network with packet tracer

[malfury77]

Hi 

sorry englis is not my mother tongue 

I want to simulate a core network with packet tracer but i don't know how to do that, 
This is a simple topo, but when a ping 192.168.1.3 from the pc 192.168.1.1 not work and the same with the other computer... but if I remove my core network and connect the sw1 and the sw2 with the links "trunk" it's work perfectly... 

I don’t understand can you help me... 

Thank you

Thanks @malfury77 

On your 'CORE', you don't configured vlan !

Add this on your 'CORE'

Ping is OK after that between PC on the same VLAN through that "CORE":
