IT WORKS! ...(Almost) My chklength isn't working. Can anyone see why
not? I'm stumped.


Good to see another cricketer on the list :)  Besides that stating "x 
isn't working" usually doesn't help us to help you.  However here it's 
obvious that you define chklength to take an argument hashes but call it 
without arguments.  You also use raw_input on one line and input on the 
next, not a good idea.  I haven't looked for anything else.
