Can't seem to get movement to work

I'm trying to get some basic movement, back and forth, rotating with left and right. I can get the movement to work but for some reason when I try to get the capsule to move up a sloped plane it just walks right through it, and everything for that matter. When using capsule collider or CController it collides below yet ignores the fact that there are objects in its' path. transform.Translate doesn't seem to work, and when I switch to a rigidbody I get undesired movement, I can paste the script if anyone can help with this
