Rule Error

Dear Friends,

I have problem with rule and tried several times to solve it but not yet
success. Hope someone can help me.

I have 2 tables : tblmasdbt and tblmasgl.

I want on every record insertion in tblmasdbt, that record also
automatically insert into tblmasdbt. I need only 2 related field.

So I create rule like this

--------------- SQL ---------------

CREATE RULE "rule1" AS ON INSERT TO "public"."tblmasdbt"

DO (insert into tblmasgl (KODEGL,NAMAREK) VALUES (new.KODEGL, new.NAMAREK));

But I always get this error :

---------- ERROR MESSAGE ----------

ERROR: column "kodegl" of relation "tblmasgl" does not exist

Here is the Table Structure

---------------------------

CREATE TABLE "public"."tblmasgl" (

"KODEGL" VARCHAR(15) NOT NULL,

"NAMAREK" VARCHAR(50),

"GOLONGAN" VARCHAR(10),

"AWAL" DOUBLE PRECISION DEFAULT 0,

"Operator" VARCHAR(3),

CONSTRAINT "tblmasgl_pkey" PRIMARY KEY("KODEGL"),

CONSTRAINT "tblmasgl_fk" FOREIGN KEY ("KODEGL")

REFERENCES "public"."tbltragl"("KODEGL")

ON DELETE CASCADE

ON UPDATE NO ACTION

NOT DEFERRABLE

) WITHOUT OIDS;

CREATE TABLE "public"."tblmasdbt" (

"KODEGL" VARCHAR(15) NOT NULL,

"NAMAREK" VARCHAR(50),

"ALAMAT" VARCHAR(75),

"Telp" VARCHAR(50),

"Facs" VARCHAR(50),

"KOTA" VARCHAR(30),

"HP" VARCHAR(20),

"Plafond" DOUBLE PRECISION DEFAULT 0,

"Operator" VARCHAR(3),

"SALDOAWAL" DOUBLE PRECISION DEFAULT 0,

CONSTRAINT "tblmasdbt_pkey" PRIMARY KEY("KODEGL")

) WITHOUT OIDS;

Hope someone could help me. Thanks a lot
