  neither `price` nor `qty' are yet defined when you try to multiply 
them, try something like this:

  require 'csv'

  puts "enter Product ID Number: "
  product_id = gets.chomp

  puts "Enter Qty: "
  qty = gets.chomp.to_f #convert string input to a float with `to_f`

  CSV.foreach("c:\plantproducts.csv") do |row|
    if product_id == row[0]
      price = row[2].to_f # fetch, convert from string, and store in 
`price variable`
      total = (price * qty)
      puts "your total is: #{total}"
    end
  end


  hth,
