You don't need to remove the line with the do, just the do keyword:

 puts "enter Product ID Number"
 product_id = gets.chomp
 CSV.foreach("c:\plantproducts.csv") do |row|
 if product_id == row[0]
   (price * qty) #The do is gone
end
end

puts "Enter Qty)"
qty = gets.chomp

You won't be able to do anything with the result of price*qty, however, unless 
you store it in a variable.
