What David said, plus, some of your male and female are strings (in double quotes) and some are just variables (no double quotes). Like here:

when gender = male

I think you meant:

when "male"

Also, the whole second case seems a bit off. case male suggests that you have a variable named male, but you don't, so it can't really work. Please read more on CASE in Ruby to understand it more thoroughly, you can start here:

I changed it a bit but i have some error about male 

puts "What is your name ?"
name = gets.chomp
name.capitalize!
puts "Hello #{name}!"

print " Are you male or female?"
gender = gets.chomp

case gender
when "male"
  puts " I have a car for you"
when " female"
  puts " i have clothes for you "
else 
  puts " Woops, we don't have anything for #{gender}"
end

case male
  when "male"
    puts "How old are you?"
    age = gets.to_i
  if age >= 18
    puts " You are allowed to vote"
   end
case female
  when "female"
    puts " Whats your date of birth?"
    femaleAge = gets.to_i
  if femaleAge >= 1996
    puts " You are allowed to enter"
    end
  end
end

your case statements are using unassigned variables male and female.

I think what you actually want is this:

case gender
when "male"
  puts "How old are you?"
  age = gets.to_i
  if age >= 18
    puts "you are allowed to vote"
  end
when "female"
  puts "Whats your year of birth"   #Note, never ask a lady this :-P
  femaleAge = gets.to_i
  if femaleAge >= 1996
    puts "You are allowed to enter"
  end
end

Hi, I noticed that you're no longer comparing cases but assigning them at he bottom of your program.

when gender = male
when gender = female

// I'm guessing should be 

when gender == male
when gender == female
