[SOLVED] Building the Cookbook example into a website.

Okay, so what I have is a website with the PHP Cookbook example which I'm trying to expand so I can use it as a portfolio piece. But I'm out of my depth here.

I have all the code working from the cookbook.php file but when I try to migrate the code I keep getting errors.

For example in recipelist.php I have a call to Render.php that outputs the recipe titles for each one in cookbook.php. But when I move it to this file I get the following error.

<h1>Cookbook: Recipes by Alena Holligan and Ken Alger</h1>

    <p>These recipes were curated from a list of recipes that are instances of the PHP Object class.</p>
    <?php echo Render::listRecipes($cookbook->getRecipeTitles()); ?>

Fatal error: Class 'Render' not found in C:\xampp\htdocs\treehouse\php\php-cookbook\recipelist.php on line 13```

And in another case, in shoppinglist.php I have the following errors

Notice: Undefined variable: cookbook in C:\xampp\htdocs\treehouse\php\php-cookbook\shoppinglist.php on line 17

Fatal error: Call to a member function getCombinedIngredients() on null in C:\xampp\htdocs\treehouse\php\php-cookbook\shoppinglist.php on line 17

```php
<?php  

            $week1 = new RecipeCollection("Meal Plan: Week 1");

            $breakfast = new RecipeCollection("Breakfast");
            echo "<br /><br />Based on the recipes currently in the Cookbook, you'll need to shop for the following ingredients... <br />";
            echo Render::listShopping($cookbook->getCombinedIngredients() );
            //echo Render::listShopping(getCombinedIngredients() );

?>

But what I don't understand is why I can't make these migrations to another file if I'm using includes. What they do as I recall is act as a "copy and paste" for code from one file into another... shouldn't it be picking up arrays and variables so I can add say the "meal plan" to one page and a shopping list to another?

I have the elements to the site that I need, I just want to separate them into different files/pages.
