APEX

Hi

I am using Apex 4.2. On a click of button a Dynamic Action is written, which calls a DB Package. The DB package has exception handlers and also the package has two output parameters

Error Code and Error Msg

So in my code(Dynamic Code) i make a call to the package and checks the value for Erroc Code.

Begin

Package call......
  If v_error_code <> '0' Then
    Raise SC_Error;
  End if;

Exception

  When SC_Error Then
    RAise_Application_error(v_err_code, v_err_msg);

End;

But when i run the page and I click I get an Internal exception error

Output from Debug -- I am not sure what the Cell in Red colour means, because the package is returning a correct message (before the red line).Can anyone help please??

Thanks
