interVLAN routing not functioning on cisco 3750

For some reason I can't ping any other VLAN from within my cisco 3750 switch from within a hyperterminal session, let alone an external device connected to a switch. THe only VLAN I can ping is vlan1 and vlan103.  Why is that? I can't pinpoint when the problem started appearring.

see my config below:

spanning-tree mode rapid-pvst
spanning-tree etherchannel guard misconfig
spanning-tree extend system-id
spanning-tree uplinkfast
spanning-tree backbonefast

any way tKalmar's last comment worked. Don't understand why I have to this but all of my vlan interfaces are up
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
