Hi,

A lot of beginners make the same mistake you did.   'Compound 
conditionals' have to be written like separate conditionals and then 
hooked together with an 'or' or 'and'.  For instance if you wanted to do 
something only if a number were greater than 5 and less then 10, you 
would do this:

x > 5
x < 10
and

if x > 5 and x < 10
  #do something
end

Everyone should use 'and' and 'or' by default instead of && and ||. 
Code reads better that way.  Only if you have a specific reason to, 
should you use && or ||.

Good luck.
