Ruby: Undefined local variable or method

Question

I'm trying to store a hash within an array with the keys "name", "number", and "email". I want the email to be a user's last name + last 3 digits of the number + "@btvs.com". I keep getting the error "undefined local variable or method" for number. How can I get this to output correctly? It has no problem grabbing the value from "name", but won't from "number".

data = Array.new()

puts "Name?, eg. Willow Rosenberg"
name = gets.chomp

    data = [
        {
        name: name,
        number: rand(1000..9000) + 1,
        email: name.split(' ').last + number.to_s[1..3] + "@btvs.com"
        }
    ]

puts data

That's because name is set before you start initializing the array/hash. Why not do the same for number? — Jonny Henly

@JonnyHenly sorry I'm a bit new to this. What should I be setting number to? — morrime

Try

puts "Name?, eg. Willow Rosenberg"
name = gets.chomp
number = rand(1000..9000) + 1
data = [
  {
    name: name,
    number: number,
    email: name.split(' ').last + number.to_s[-3, 3] + "@btvs.com"
  }
]
puts data

Why did you change number.to_s[1..3] to number.to_s[-3, 3]?

Because he said the last three digits of the number.

Try [code dump] with no explanation, leads to comments like my previous comment.

@morrime I think you should open another question. but before try on your own and tell us where you find difficulties.

@morrime Sorry if I came off as sounding rude, that wasn't my intent. If you're having trouble learning Ruby, then you should check out Codecademy's Ruby Course, it's free, it's hands-on and does a pretty good job of conveying information.
