print “How many Children do you have?”
user_num = Children(gets.chomp)

if user_num < 0
puts “Sorry, you are not eligble for children’s free pass!”
elsif user_num > 0
puts “congrtulations, you are eligble for children’s free pass!”
else user_num = 0
puts “sorry, you are not elible for children’s free pass!”

Please help, what am i doing wrong here?

Not aware of any Children() method in Ruby.

print "How many children do you have? "
user_num = gets.chomp

Hi, this is the answer I get:

How many children do you have?3
comparison of String with 0 failed

I think i am missing a string to link number of children up?

gets means literally, get string which means the user input is a string value.

 if user_num.to_i > 0

 if user_num.to_i < 0

 if user_num.to_i == 0

I just figured it out.
I was missing Integer
user_num = Integer(gets.chomp)

Thank you for your prompt response and help!
