C#: WinForms User Control Object reference not set to an instance of an object

Hi

Using the TMDB API
I have a User Control on a winform with a TvTitleLbl Label & TvPosterPictureBox

I've been strangling to extract the year from KnownForTV.FirstAirDate having finally got it working, is this the best way?
I'm now getting Error, "Object reference not set to an instance of an object" on both the Label & PictureBox when trying to set it's properties unsure why ?


the proper lable.text will be "TvTitleLbl.Text = "TV: " + pKFTV.Name + " ( " + year.ToString() + " )";"  shortened it to debug
