Basic Input Handling

http://pastebin.com/U50W5WUS
I have to input something twice times before It actually reads the input.
Please help thanks.
Also if I want it so whenever someone enters something that isn't in the put to say "Sorry, what?"
and then to restart the whole program again.

Split into new topic. A title was provided for you.

You put "input = read()" twice. Remove the first occurrence.

Also, to restart, don't shell.run() the file AGAIN. That's bad. Very bad. Instead, use a loop, such as a while loop. Wrap the whole thing in something like "while true do", and you're set. Don't forget to put an "end" at the very end!
