error in action of adding new rows

I'm having a problem with an action that adds rows to another table. I have an event that when it is fulfilled this action is executed but it gives me this error (Failed: Error: Object reference not set to an instance of an object. Error: 'Add Row' Data action ''Add Row' Data action 'Add in box'' failed with exception Object reference not set to an instance of an object. )
Any suggestion is welcome.
Cheers
