Hi. Can anyone tell me what's wrong with this statement?

CREATE TABLE RESERVAS_STOCK(CODIGO_DEPOSITO D_CODIGO_DEPOSITO NOT NULL,
NUMERO_TERMINAL SMALLINT NOT NULL,
CODIGO_PRODUCTO D_CODIGO_PRODUCTO NOT NULL,
CANTIDAD INTEGER NOT NULL CHECK(value > 0),
TIPO_RESERVA SMALLINT NOT NULL CHECK(value in (1,2)));

It returns:
Unsuccessful execution caused by system error that does not preclude
successful execution of subsequent statements.
Dynamic SQL Error.
SQL error code = -901.
Illegal use of keyword VALUE.

Using FB 1.5.3

Regards!!
