>Thanks a lot Cetin!!!! The problem was on the tables property. I was using the name of the local cursor in both parameters.

It's good to see you solved your SPT problem, just a recomendation: do the Message(s) after your SQLROLLBACK(..), the transactions must be short, if your user doesn't see your message, the process could block all the users.

IF !TABLEUPDATE(0,.f.,"NominaPopular")
  lcError=''
  Aerror(arrCheck)
  For ix=1 to 7
    lcError = lcError+trans( arrCheck [ix])+ chr(13)
  Endfor
  SQLROLLBACK(Thisform.ConnHandle)
  MESSAGEBOX(lcError,0,'Error def')
  WAIT WINDOW "NO SE pudo Actualiza La Tabla 1"
  RETURN 0
ELSE
