我被困在決策部分。當答案變量是N（當我鍵入n這意味着我不希望在不同的行打印文本）和標誌着變量爲Y（當我Y型那就意味着我不想打印帶引號的文本），我收到消息：答案'Y'無效。程序正在終止。下面是代碼：Ruby中的決策錯誤
def multiFunctionalPrinter
puts "How many times do you want to print?"
number = gets
puts "-------------------------------------------"
puts "What do you want to print?"
text = gets.chomp #chomping variable to format it for decision making
puts "-------------------------------------------"
puts "Do you want to print in different lines (Y or N)?"
answer = gets.chomp #chomping variable to format it for decision making
puts "-------------------------------------------"
puts "Do you want to add quotation marks (') (Y or N)?"
marks = gets.chomp #chomping variable to format it for decision making
if answer == "Y" && marks == "Y" # Different lines: ON , Quotation marks: ON
1.upto(number.to_i) {puts "'" + text.to_s + "'"}
elsif answer == "Y" && marks == "N" # Different lines: ON , Quotation marks: OFF
1.upto(number.to_i) {puts text.to_s}
elsif answer == "Y" && marks != "Y" || marks != "N" # Different lines: ON , Quotation marks: INVALID
puts "Answer '#{marks}' is invalid. Program is terminating."
elsif answer == "N" && marks == "Y" # Different lines: OFF , Quotation marks: ON
puts "Do you want to split what you print? (Y or N)"
answer2 = gets.chomp
if answer2 == "Y" # Split: ON
1.upto(number.to_i) {print "'" + text.to_s + "' "}
print "\n"
elsif answer2 == "N" # Split: OFF
1.upto(number.to_i) {print "'" + text.to_s + "'"}
else
puts "Answer '#{answer2}' is invalid. Program is terminating."

我在做什麼錯？
