#new code
puts "Enter Product ID Number"
product_id = gets.chomp
CSV.foreach("c:\plantproducts.csv") do |row|
 if product_id == row[0]
 (price*qty) == subtotal
 puts "Enter Quantity"
quantity = gets.chomp

end
end
subtotal = (price * quantity)
puts subtotal


I don't understand why price is an unidentified variable... is the 
current code not reading it in the CSV file and giving it as an output?
