DHCP and Internet issue on Catalyst 2960

[sdfnasdf8]

So, I have a Catalyst 2960 that has 12.2 (55) installed on it and basically turned it into a Layer 3 switch. I have the default VLAN 1, VLAN 10 and VLAN 20. 

VLAN 1 - Ports 1-12 - 192.168.1.X

VLAN 10 - Ports 13-24 - 192.168.10.X

VLAN 20 - Ports 25-36 - 192.168.20.X

Issue - If I plug any PC into VLAN 10 or 20, I'm not getting a DHCP address from my Cisco E3200 router with DD-WRT. If I plug a PC into VLAN 1, I'm getting a DHCP address and Internet access. 

I made a static route on my router and now I verified I can ping between VLANS on the switch, but I'm not sure why VLAN 10 and VLAN 20, devices aren't getting a DHCP address and Internet. I tried using a static IP Address, but no Internet access. Any help would be appreciated.

Thanks

Did you configure DHCP forwarding on the switch?  E,g.

interface vlan 10
  ip helper-address <ip address of dhcp server>

Has the DHCP server got a scope configured for VLAN10 and VLAN20?

Ok, I've now configured DHCP forwarding on the switch. Now I just need to figure out how to setup DHCP scopes on my dd-wrt Cisco E3200.
