New Item Function Issues

[Abronsyth]

For some reason it seems to just keep resetting it to 0.

Here is the function currently:

PHP Code:

function items_health($item, $adopt){
  $mysidia = Registry::get("mysidia");
  $addHealth = $adopt->health + $item->value;
      //Check if the adoptable's health is already at maximum.    
  if($adopt->health = 100){
    $note = "Your gryphon is already fully healed! The {$item->itemname} was not used.";
  }
  //Not a maximum, but don't go overboard!
  elseif($addHealth > 100){
    $mysidia->db->update("owned_adoptables", array("health" => 100), "aid ='{$adopt->aid}' and owner='{$item->owner}'");
    $note = "The {$item->itemname} fully healed your gryphon!";
    $delitem = $item->remove();
  }
  //Not at maximum, won't go overboard. Proceed.
  else{
    $mysidia->db->update("owned_adoptables", array("health" => $addhealth), "aid ='{$adopt->aid}' and owner='{$item->owner}'");
    $note = "The {$item->itemname} raised your gryphon's health by {$item->value}! Their health is now at {$addHealth}.";
    $delitem = $item->remove();
  }
  return $note;
} 


The health is at 0, and when I use the potion it now tells me that my pet is already fully healed, and it doesn't use the item up, but the health is still 0.
