Probleme » particle collide problem

Hi,

where is my mistake? Particle wont collide with the grid. They should slide or bounce. better both. And why I dont have a preview of my smoke sim?

Last but not least: Where I'm able to find detailed! Tutors with as muach as possible colliding stuff in it. Particles of course.

Thank You!!!

I didn't find the right solution from the Internet.
