Added DMZ interface, does not show in services>DHCP setup

[dvh]

I am very new to pfSense, so I probably have missed something simple, but I do not seem to be able to setup a DMZ appropriately.  I am following one of many online help procedures, but I am stuck very early in the process.  I have added the interface "DMZ", but when I go to the services>DHCP server, I do not see my new interface as a tabbed option.  I tried a reboot, but no change.  what am I missing?

sorry. my bad.  I had the /32 option configured, which would of course not allow any more hosts.  CHanged to /24 and now the interface shows.
