I have no error, when i say "no funciona" i mean that i try to verify if department_id is divisible by 10, if it's no disible it shouldn't insert any row into "departamento" but it doesn't verify anything and always insert the record when i do

"insert into departamento values (111,'Merchandising',123,456)" for example when i write this instruction should appear the message "Holita esto esta mal" and it doesn't.

thanks for answering so fast

PD.: Por cierto por si alguna otra persona lee, soy español y lo hablo y lo escribo también, por si me quisieran responder
