ya know what's funny, kurt has a tutorial on how to do a leg setup, and it's only 2 points... if ya have any points, check it out. other than that, i'm still surfing the web to see if i find any step-by-step tuts that might make life a little easier...

if i were to just watch the video and take a guess as to what you're doing wrong, the only thing i can come up with is the last orient constrant (the one that flipped the foot), cause you didn't go into your option box, and there might be something there that could reverse the effect you have *shrug*
