For really odd things like "a TV programme list", MODx is not any help at all. I’m afraid it’s just not been going long enough for there to be a ready-made module for your every whim.
If you cannot program PHP, and find zi’s post too technical, and find it difficult to abstract your request, you are not going to be able to get MODx to do this.
Alternatively, if only one person needs to add TV programmes, can they not just add it in HTML?
I have to display a list of (TV)progammes daily. A person should be able to add the programmes for each day.
May I ask why you have to do this? Is this your homework from Programming Class?
Have you tried
Calendar?
