You'll have to be more specific. What is the objective here? What does this do? What do you need help with? Do you need an explanation as to what's going on here?

I have no idea what it is doing...he says it is giving him 14, but ...
I told him the function is saying if the length of x is 14 then he will get a prompt saying win...
otherwise fail...

is that right???

this code, in generaly, intent to check a realy simple password.
its a game - if you guess the password that you win else you loose.
ive added a simple application that can show it in an html page
its quit simple - if you enter the right length value than you win else you loose.
copy the code (its your code with some user interface addin) to notepad than  save it as HTML file on your desktop.
open the file (dbl click) and try to find out what is the password :-)
the answer is: any input that its characters length is exactly 14 (thats the value of 'moo' variable).
good luck!
