Cisco Firewall :: 3560x Cannot Communicate From Inside To DMZ

I have an existing ASA Firewall that is configured with an inside interface and an outside interface - communications is working fine in this configuration.I am trying to add a DMZ interface that will be connected to a 3560x switch - the new ASA and Switch configuration are below. [code] I cannot ping from a computer on the LAN (10.10.10.3) to the IP address of the DMZ Switch on VLAN 510 (10.50.10.1).I can, however, ping from the DMZ Switch (10.50.10.1) to the workstation on the LAN (10.10.10.3)
