  You're declaring variables instead of parameters. You'll simply insert null values.

  Whatever you are declaring inside your begin try - end try block, does not have any value assigned before insert statement. This is resulting in NULL insertion, thus you are not seeing anything. Something like this will return something:

   declare @titolo1 varchar(50)    =    '1',
      @rif1 varchar(50)        =    '2',
      @postiVac1 int            =    '3',
      @Dip1 varchar(50)        =    '4',
      @liv1 int                =    '5',
      @paC1 varchar(50)        =    '6',
      @car1 varchar(50)        =    '7',
      @cat1 varchar(50) =NULL,
      @sotcat1 varchar(50) =Null,
      @ref1 int                =    8

     BEGIN TRAN
  select @titolo1, @rif1,@postiVac1,@Dip1,@liv1,@paC1,@car1 ,@cat1,@sotcat1,@ref1

  Since this is a CRUD procedure, and as Luis said, you should be adding the variables as input parameters for the procedure for CREATE & UPDATE operations.
