HP switch 1820 VLAN issues

[Shanintracouae]

I brought HP Switch 1820 recently, I have a firewall Fortinet 80c our office we restructured the cabling in a few days back after the cable our IT dept thing we need to separate the network with VLAN technology one for the PC user and Voice, Management Users and Wifi/guest users.

Network Topology is

IN Fortinet Firewall LAN interface: VLAN 10 192.168.0.0/24( Office PC and Voice), VLAN 20 192.168.10.0/24 (management ) and VLAN 30 10.10.1.0/24 

Fortinet I done the configuration same VLAN configured as I mentioned above 

In HP 1820 Switch also I configured VLAN 10,20,30 and Untagged 

After that, I try to ping connect all the VLAN port I can not ping all the gateway of Fortinet VLANs 

if anyone has the idea please help me otherwise, I need to buy layer3 switch I don't know management will accept
