I can't Ping other subnets but pinging within subnet is successful

[JulNazz]

Hi, I'm new with cisco packet tracer. But I have a problem with my project file, I filled in all the IPs but i cant ping them from other subnets. I tried following the tutorials on Youtube but still no success. Please anyone could try to point out what is wrong correct my mistakes. Please, Thanx in advance.

I do not use packet tracer and so can not examine your file. But what you describe suggests that you have configured this on switches that are operating as layer 2 switches (no switch that has ip routing command). Layer 2 switches forward frames within each vlan but can not forward frames between vlans. To forward frames between vlans requires layer 3 forwarding capability which is activated with the ip routing command. Once you have configured ip routing on at least one switch and have configured vlan interfaces (and specified an IP address for each vlan interface) on that switch for each vlan then you should be able to ping between vlans.
