HP Procurve 2910 VLAN routing to Cisco ASA Issue

I have a Cisco ASA 5510 as my firewall.  the ASA is connected to an HP Procurve 2910.  I have a couple of VLANs configured on the Procurve.  Only the VLAN with the connection to the ASA  (VLAN 10)  can access the internet.  

How do I create a route for the other VLANs to the internet?  My Procurve config is listed below:

hostname "ProCurve 2910al-48G Switch"
module 1 type J9147A
ip routing
vlan 1
   name "DEFAULT_VLAN"
   untagged 21-48
   ip address dhcp-bootp
   no untagged 1-20
   exit
vlan 10
   untagged 1-10
   ip address 10.117.7.1 255.255.255.0
   exit
vlan 20
   untagged 11-20
   ip address 10.117.5.1 255.255.255.0
   exit
ip route 0.0.0.0 0.0.0.0 10.117.7.254
snmp-server community "public" unrestricted
password manager
