The And (&&) Operator challenge help

I just don't understand what I'm doing wrong in this challenge here. Here's my error: SyntaxError: 8e514218-e8eb-49b8-b0da-ccbdd9bd5e89.rb:18: syntax error, unexpected end-of-input, expecting keyword_end but I don't understand what's wrong with my Syntax.

ruby.rb 
def check_speed(car_speed)

  car_speed = gets.chomp.to_i

  if (car_speed >= 40) && (car_speed <= 50)
    return "Safe."

  elsif (car_speed > 50)
    return "Unsafe."

end

Hey Taylor,

There are a few issues with the code. One syntax and a few that just don't comply with what the challenge is asking for (it can be very picky).

First, the syntax error: you are missing the end after the if statement

Second, you are using an elsif when it should be an else. You are only checking for one if condition, and if that is not met, then you move to an else not an elsif.

Now, for the Picky Challenge: 1. It wants you to return "safe" -> Lower Case and NO period. 2. It wants "unsafe" -> same thing (lower case and no period). 3. The challenge never asked you to code an input for car_speed, so that needs to be deleted.

With the exception of the one missing end, your code is correct, it just needs to be exactly what the challenge asks for, otherwise the code checker will fail and return "Bummer".

def check_speed(car_speed)

  if (car_speed >= 40) && (car_speed <= 50)
    return "safe"

  else
    return "unsafe"

  end
end

Hope this helps. Keep Coding! :)

You just need to put another 'end' at the bottom of your code! The if statement needs an 'end' and the def statement also needs to close with an 'end' :)

Ohh, okay! So do I have to have a end after every single If, Else, Elsif?

Oh wait I understand, I didn't have an end for the 'def'. Thanks so much for your help!
