Notice: Undefined index: catagory in /home/treehouse/workspace/inc/functions.php on line 17

here is my code from the page the error referenced

<?php
function get_item_html($id, $item){
  $output = "<li><a href='#'><img src='"
            .$item["img"]
            ."' alt='"
            .$item["title"]."'> 
            <p>view details</p> 
            </a></li>";
  return $output;
}
//catagory is in data.php as a $catalog array key
function array_catagory($catalog, $catagory){
  $output = array();

  foreach ($catalog as $id => $item){
//    catagory passed compared to catagory looped through
    if(strtolower($catagory) == strtolower($item["catagory"])){
//      if true add the id to $output array
      $output[] = $id;

     } /*if*/
   } /*foreach*/
  return $output;
} /*call fn from catalog page*/
//go to index.php, copy call to fn array_rand AND foreach loop

insight is appreciated

could be a spelling mistake, if you're getting a value from the database. 'category'. This glitch usually means there's a discrepancy between what is in a value and what you think is in it. you can use var_dump to see what is in $item. something like:

var_dump($item);
exit;

yes, it was a spelling error. Mom was right...I should have paid attention in grammar school 0.o).
