How do I fix this?

[longsally]

We adopted a small kitten today. This is my 4th cat in my lifetime and every cat I have ever brought home, I just showed them the litterbox and that was that. Well, This new baby was shown the litter box several times today and yet he pee'd on my bed. I immediately picked him up and placed him where the litterbox is ( I have another car for 3 years now) and I put his paws in the litter and scratched them in. He jumped out of the box and pooped on the floor next to the litterbox. I am perplexed. What am I doing wrong and how can I jump right on this problem? I dont want bad habits to start.
