Hi James,

You're very close. This code should work:

name = gets.chop.downcase
if name != "bob" || name != "fred"
 puts "That wasn\'t one of the choices."
else
 code

You have to have a full expression for each part of the conditional.
What was happening previously was this:

The if statement checked the expression: name != bob
Then the is statement checked the expression: "fred"

In Ruby, anything that is not nil or false is considered true. Thus
"fred" is considered true.

I hope this has explained your problem :)

Thanks,
Sam
