I have encountered the exact same problem and I was wondering whether you will be able to help.

prices= {
stock= {

for fruits in prices:
print fruits
print "Price: %s" % prices[fruits]
print "Stock: %s" % stock[fruits]

Unable to move ahead to the next level

the validition is case sensitive (price vs Price)


Wow, that did the trick! lol
thanks for your help!
