Updating checkbox field based on values from repeater field

[Tyssen]

I'm using a repeater field for holding stock levels of different items and when all the rows' quantity columns equal 0, I want to set another stock checkbox field to off.

I'm doing this in the template that displays the product:

foreach($page->inventory as $stock) :

  $stock_total += $stock->qty;

  if($stock_total==0) :
    $page->of(false);
    $page->stock = false;
    $page->save();
  endif;

endforeach;

but it's setting $page->stock to off whenever the page is refreshed regardless of whether $stock_total = 0 or not. Why is that?

Never mind, realised my problem about 30 seconds after posting. :/
