pack() and the division of vertical space

I am trying to figure out how to stack two widgets in a frame
vertically so that they both expand horizontally and during vertical
expansion, the top one sticks to the top of the frame and the bottom
one consumes the remaining vertical space. I thought this would do it
but it doesn't. What am I missing?

from Tkinter import *

class AFrame(Frame):
def __init__(self,master,**config):
Frame.__init__(self,master,config)
size=50
self.l1= Label(text="abc",relief="groove")
self.l1.pack(side=TOP,expand=YES,fill=X,anchor=N)
self.l2= Label(text="abc",relief="groove")
self.l2.pack(side=TOP,expand=YES,fill=BOTH)

af= AFrame(None)
af.pack(side=TOP,expand=YES,fill=BOTH)
mainloop()

.

... But the fields have to be cleared also, meaning they can show in the window but internally they need to be cleared, because when the user types a part no for the first field the rest of the fields are dependent on this part no and the window will adjust based on the number fo fields. ...
