Subproducts: Attributes stocks summed during permutations creation

guys,

i dont know why the attribute stocks are summed during permutations creations. imo, it should be the least attribute stock. (i know thats is a warning on the top of the page saying "Settings you put here for stock will be summed to give a default stock amount for each subproduct.")

example:
variation: color
attribute: green
stock: 100

variation: size
attribute: big
stock: 200

so should be 100 big green stairs, not 300.

to correct this, change this code (in subproducts.inc)

    foreach ($permutation as $vid => $aid) {
      $form['name'][$fields][$aid] = array('#type' => 'markup', '#value' => $variations[$vid]->attributes[$aid]->name);
      $price += $variations[$vid]->attributes[$aid]->surcharge;
      $stock += $settings[$vid][$aid]['stock'];
    }

to this

    $stocktoggle = 0;
    foreach ($permutation as $vid => $aid) {
      $form['name'][$fields][$aid] = array('#type' => 'markup', '#value' => $variations[$vid]->attributes[$aid]->name);
      $price += $variations[$vid]->attributes[$aid]->surcharge;
      if ($stocktoggle != 0) {
        $stock = ($settings[$vid][$aid]['stock'] >= $stock) ? $stock : $settings[$vid][$aid]['stock'] ;
      }
      else {
        $stock = $settings[$vid][$aid]['stock'] ;
      }
      $stocktoggle += 1;
    }

PS: the instructions on the top of the page will continue to show "Settings you put here for stock will be summed to give a default stock amount for each subproduct."

regards,
