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
