wrong dhcp from WLAN VLAN

We have a HP SWITCH with a ZD on port 44, an access point on port 37, a laptop on 35, and a firewall on port 36. We have the default vlan1 on ip 10.x.x.x and vlan2 on 192.x.x.x. We have 2 wlans 1> for vlan1 and 2> guest for vlan2 and in the ZD WLAN advanced options for VLANS they are given the vlan of 1 and 2 respectivly.

The laptop gets the right dhcp for 192.x.x.x, but the wlan clients get random ip's when they connect to the wireless of either 10.x.x.x or 192.x.x.x

my switch config is

hostname "fred"
ip default-gateway 10.x.x.254
ip routing
vlan 1
untagged 1-34,38-48
ip address 10.x.x.x
tagged 35,37
no untagged 36
vlan 2
name "GUEST"
untagged 35-37
ip helper-address 10.x.x.x
ip address 192.x.x.x
tagged 44
snmp-server community "public" unrestricted
no autorun
password manager

Can you help?

Why do you need Vlan2 on port 44 (ZD), even tagged? ZD needs only to communicate with AP over the VLAN1.
And do you mean that guests connecting to WLAN2 get addresses from different subnets? As clients connecting to different WLANs have to get different subnet's addresses.
Do you have DHCP server allowed on firewall?
