Hola a todos! Tengo problemas con la siguiente transacción, al ejecutarla las variables del prompt, sólo me pide valores para algunas en vez de para todas, y tambien me dice que "la variable w_street_2 no está declarada" cuando claramente está en el DECLARE arriba del todo, no sé si tendrá mas fallos porque después de dar ese mensaje se para. Aquí os dejo el código.
