Gm Command why i only can do /field

here is my hotuk
*ADMIN_NAME "a"
*ADMIN_COMMAND "a" hello1"
*ADMIN_COMMAND "a" hello2"
*ADMIN_COMMAND "a" hello3"

My Char name is=a
when i log in game i only can use /field
exp: i typed /field 6 then i tele to Phil
and this is wat i wonder when i type ~/hide then the chat box appear hide ok <---is that mean i can use admin2?
when i tried to get admin2 and 3 wat should i type in game?
is Admin1 can use admin 2 and 3 command?

you type /:a hello3 <admin level 3>

The only way to use all comands typing / in the begining is being a GM Lvl 3...do what Lord said and everything may work correctly ; )
