Treehouse TeacherHi there! I feel fairly certain this is due to a typo. Check out this line:
echo "\n" . $ing["amount"] . " " . $ing["measeure"] . " " . $ing["item"];
It's looking for something at the key of "measeure", but that should be "measure".
echo "\n" . $ing["amount"] . " " . $ing["measure"] . " " . $ing["item"];
Note the removal of the extra "e" from "measeure" to "measure".
Hope this helps!

13,552 PointsThis DID help some! Sorry, nothing worse than a dyslexic trying to code! After correcting this, I'm still getting
PHP Fatal error: Uncaught Error: Call to undefined method Recipe::getInstruction() in /home/treehouse/workspace/cookbook.php:22
Stack trace:

thrown in /home/treehouse/workspace/cookbook.php on line 22

Any other suggestions? I've been hung up here for hours!

Treehouse TeacherOn this line you're calling the getInstruction()
function.
echo implode("\n", $recipe1->getInstuction());
It's the last line in your cookbook.php
. Unfortunately, you don't have a getInstruction
function currently. You do however have a getInstructions
function. Notice the difference between singular and plural. You have this as the next to last function in your recipe.php
file.
public function getInstructions() {
return $this->instructions;
}
I believe that the first line I mentioned should be altered to:
echo implode("\n", $recipe1->getInstuctions());
Hope this helps!
