Undefined index: amount in F:\xampp\htdocs\nauka\cookbook.php on line 18

I have a bug, I have looked through the code 10 times and I have no idea how to fix the code. So I ask for help. For every hint I would be very grateful. I would prefer a hint rather than a ready solution, because I want to understand the idea of programming :-)

I've got 2 Notices:

My First Recipe Notice: Undefined index: amount in F:\xampp\htdocs\nauka\cookbook.php on line 18 Egg Notice: Undefined index: amount in F:\xampp\htdocs\nauka\cookbook.php on line 18 cup Flour

And my code is:

recipe.php

<?php

class Recipe
{
  private $title;
  public $ingredients = array();
  public $instructions = array();
  public $yield;
  public $tag = array();
  public $source = "Alena Holligan";

  private $measurements = array(
    "tsp",
    "tbsp",
    "cup",
    "oz",
    "lb",
    "fl oz",
    "pint",
    "quart",
    "gallon"
  );

  public function setTitle($title)
  {
    $this->title = ucwords($title);
  }

  public function getTitle()
  {
    return $this->title;
  }

  public function addIngredient($item, $amount = null, $measure = null)
  {
    if ($amount != null && !is_float($amount) && !is_int($amount))
    {
      exit("The amount must be a float: " . gettype($amount) . " $amount given");
    }
    if ($measure != null && !in_array(strtolower($measure), $this->measurements))
    {
      exit("Please enter a valid measurement: " . implode(", ", $this->measurements));
    }
    $this->ingredients[] = array(
      "item" => ucwords($item),
      "amonut" => $amount,
      "measure" => strtolower($measure)
      );
  }

  public function getIngredients()
  {
    return $this->ingredients;
  }

  public function displayRecipe()
  {
    return $this->title . " by " . $this->source;
  }
}

cookbook.php

<?php

include "classes/recipe.php";

$recipe1 = new Recipe();
$recipe1->source = "Grandma Holligan";
$recipe1->setTitle("my first recipe");
$recipe1->addIngredient("egg", 1);
$recipe1->addIngredient("flour", 2, "cup");

$recipe2 = new Recipe();
$recipe2->source = "Betty Crocker";
$recipe2->setTitle("My Second Recipe");

echo $recipe1->getTitle();
foreach ($recipe1->getIngredients() as $ing)
{
  echo "\n" . $ing["amount"] . " " . $ing["measure"] . " " . $ing["item"];
}

I believe you have a spelling error in this section:

$this->ingredients[] = array(
      "item" => ucwords($item),
      "amonut" => $amount,  //this should be "amount" => $amount,
      "measure" => strtolower($measure)
      );

Make that correction and see if it helps! :sparkles:
