你正在嘗試做多，以在一個地方嘗試這個

def convert_currency(amount,choice) 
    converted_amount = choice == 1 ? amount/3.65 : amount * 3.65 
    from, to = choice == 1 ? ["Qatari Riyals", "US Dollars"] : ["US Dollars","Qatari Riyals"] 
    puts "Your choice is to convert #{sprintf('%.2f',amount)} #{from} to #{to}; You get #{sprintf('%.2f',converted_amount)} #{to}" 
end 

puts "Please Enter an Amount" 
user_amount = gets.to_f 
choice_convert = nil 
while ![1,2].include?(choice_convert) 
    puts "Enter your choice: 1 for converting Qatari Riyals to US Dollars" 
    puts "Enter your choice: 2 for converting US Dollars to Qatari Riyals" 
    choice_convert = gets.to_i 
end 
convert_currency(user_amount,choice_convert)
