print user_input = gets.chomp.downcase!

if user_input.include? "s"
    print "hello"

I am confused as to why it returns an error.
The code says "undefined method `include?' for nil:NilClass"
and Codecademy says "Oops, try again. Your code doesn't look quite right. Check the first exercise if you need help!"


This is what worked for me

print "What is your name?"
user_imput = gets.chomp
if user_input.include? "s"
put "nothing to do here!"
