Dell Switches and VLANs

I cannot seem to figure out how to connect two switches together over a VLAN.  This is my situation.

On one switch, i have one subnet, 192.168.20.x.  On Port 24 of this switch, i created a vlan with a number of 4000 and set mode to general and Tagged on that port. Connected to this switch, i have another dell switch which handles all 10.10.10.x traffic with a firewall that hands out DHCP at 10.10.10.1 that plugs into the switch.

I have another switch on the same subnet connected via RJ45.  On this switch i also have port 24 tagged to 4000, also tagged and set to general.  In this switch i have a computer system sitting on the 10.10.10.x subnet.

However, i cannot get traffic to pass along that VLAN at all.  No ping traffic, etc.

How would i solve this issue?

Thanks,

You description is very cryptic.  Let me see if I have it right.
3 dell switches.

Switch 1 has default vlan1 on all ports except #24 which is assigned to vlan 4000
vlan1 is on 192.168.20.0 network

Switch 2 has a network 10.10.10.0, all ports assigned to vlan1 (default) and has a DHCP firewall attached to it (and I assume is the internet gateway?)
Switch 2 is connected to switch 1

Switch 3 is connected to (?) switch 2 (?) and has a workstation connected that is on the 10.10.10.0 network (which means switch 3 must be connected to switch 2 and getting dhcp from the router connected to switch 2).

The system seems somewhat convoluted.  I need to know what your ultimate goal is.  Is it to allow the 192.168.20.0 network to get to the internet router, or to allow them to talk to the 10.10.10.0 network?  Or something else?

I attached a image of what exactly needs to happen.  Hopefully it will clarify what i am asking for.

Please print the attached grahpic and I am going to refer to labeled items.  
You will need to allocate 2 ports each on switch-2 and switch-3 for trunk ports, and one port each on switch-1 and switch-4.

Note: Trunk ports can transfer packets from all vlans across a single wire while keeping each vlan separate.

All ports on switch-1 and switch-4 (except the trunk port) need to be assigned to vlan-4000.

NO ports in switch-2 and switch-3 need to be assigned to vlan-4000.

All ports on switch-2 and switch-3 (except the trunk ports) need to be assigned to vlan1 (default)

The trunk ports will allow vlan-4000 traffic to flow through them without affecting vlan1 (network 192.168.20.0)

Any other cables connecting any of the switches together will not be needed as the trunks can handle all traffic.

Vlan-4000 members should be able to get DHCP from firewall 10.10.10.1.  
Make sure that the default gateway for everybody on vlan-4000 is 10.10.10.1 mask 255.255.255.0

This should work if I got your configuration correct.
Let me know.  Deon
