Error registering in Mysql [closed]

I'm trying to register with form of the system, however I'm getting the following message:

Error : 

  Cannot add or update a child row: a foreign key constraint fails
  ('gpiweb_pdi'.'avaliacoes_simulados', CONSTRAINT
  'fk_usuario_cadastro_avaliacoes_simulados' FOREIGN KEY
  ('usuario_cadastro') REFERENCES 'usuarios_acesso' ('id_usuario') ON
 DELETE NO ACTION ON U)

Would anyone know what it can be and how to solve it?

Thank you

Verify that you are setando or user id at the time of your transaction . he is complaining that the fk user can not be null .

Where do I find applications projects made in phonegap ready for editing? How to get the result of a JUnit assertEquals test and why in a String type variable?
