I have created a dictionary and can't get the input to add another unit to the dictionary.  It will only take the last entered value.  If you have a hard time understanding this, here is a sample(not verbatum):

The problem is that you're overwriting the dicitonary through each loop:

---
def menu1():
  v1=raw_input('...')
  v2=raw_input('...')
  c=raw_input('...')
  l=[]
  while c>0:
    n=raw_input('...')
    d={'a':v1, 'b':v2, 'c':n}
    c=c-1
    l.append(d)
  return d

print menu1()
