Alright. I want it so the following would happen, Heres a sample:

```
puts "what would you like to see?"
var = gets.chomp
if var == "z"
  puts "this"

elsif var == "d"
  puts "stack"

elsif var == "y"
  puts "overflow"

else
  puts "I don't understand that."

end

```

Currently it works fine up until I want to have the user redefine the 'var'. Currently all the loops just loop back the puts from the elsif - i want it to ask for the user input again, then print out the elsif to that.
For example:  

User types in `y`, the code would say `overflow`, then return to line 1. Any help would be awesome.
