RPG Movement system - help!

[nexxy]

How can I set a movieclip to move to wherever the mouse was clicked, like a person walking to the clicked position BUT I want to be able to make it stop if it encounters a wall, and then not be able to move through that wall. I have basic experience in flash, and I know my way around, but I have no clue how I would go about doing this. All help is appreciated!
Thanks!
