Collision Detection

Hi guys, I have as2 and flash 8.0.

Um… I am new to this forum and flash but I am used to programming and game making.

I am making a game and am facing collision problems. I have looked at nearly every tutorial on collision on net. I want my wall to just be solid and so that my player can walk on it(platform). Can anyone help, please? Or can anyone just point me to a tutorial or something.

                           Thank u for ur help.
