I found this two columns with combinations and combinations attributes. My problem: if my main product is out of stock i can see: delivery in 2 weeks, but if customer choose main product + attribute from combination, he can see added attribute available date. So in the result: I dont have main product and it takes 2 weeks to ship, but if customer choose main + accessorie it shows: 1 -3 days delivery.

 

I didnt find any info in product.js file so the problem in product. tpl yes? 

if ($product->quantity <= 0) { 
available_date['date'] = '{$combination.available_later}'; 
} else {
available_date['date'] = '{$combination.available_date}';

its my way, but it not works. Help me if u know how
