Trying to do a fact and dim table in Sql

so far this is what i have code wise, but im getting an error 1239 . Is it not referencing something correctly .

CREATE TABLE CustomerDim ( C_CustomerID_Cu INT(10) NOT NULL, C_FacilityReservationNumber_Cu INT(10) NOT NULL, I_EventCode_Cu INT(10) NOT NULL, CONSTRAINT C_CustomerID_Cu FOREIGN KEY (C_CustomerID_Cu) REFERENCES CustomerDIM ); CREATE TABLE RoomDim ( C_RoomNumber_Ro INT(10) NOT NULL, C_RoomType_Ro INT(5) NOT NULL, C_RegionID_Re INT(4) NOT NULL, C__ResortCode_Fa INT(10) NOT NULL, CONSTRAINTC_RoomNumber_Ro FOREIGN KEY(C_RoomType_Ro) refereREFERENCES nces RoomDIM ); CREATE TABLE ReservationFact ( C_RoomReservationNumber_Rr INT (10) NOT NULL, C_CustomerID_Cu INT (10) NOT NULL, C__RoomType_Ro INT (10) NOT NULL, C_D_ArrivalDate_Rr DATE, C_EmployeeNumber_Em INT (5) NOT NULL C_ResortCode_Rs INT (10), CONSTRAINT C_RoomReservationNumber_Rr_pk PRIMARY KEY (C_RoomReservationNumber_Rr) );
