var TOTAL_PRICE = 0, TOTAL_WEIGHT = 0;

function get_price_for_all_variants_for_searched_categories(products){

    return CATEGORIES_SEARCHED_FOR.indexOf(product.product_type) !== -1;
  });

  // For each product category that is searched for
  $.each(PRODUCTS, function(i, product){
    // For each variant of a lamp or wallet
    $.each(product.variants, function(j, variant){
      // If it is available, add the price to the total price and add the total weight for shipping cost.
      if(variant.available){
        TOTAL_PRICE += parseFloat(variant.price); TOTAL_WEIGHT += variant.grams;

function displayResult(price){
  // Log the price in the console
  console.log('Cart subtotal: $' + TOTAL_PRICE);
