new module to calculate the Volume loaded

[jvpolivares]

Hi there,

 

I'm trying to create a new module to calculate the volume of products, in the cart.

The max volume is a constant, the container capacity,

 

in container.php, I define the variable

 

$smarty->assign('Volumen',0);

 

in container.tpl

 

foreach (from=$products item=product name='myLoop')

{

$Volumen=$Volumen+($cart_qties*$product.supplier_reference)

}

{$Volumen}

{l s=' % Loaded'}

 

 

even if I only put in container.tpl

{$Volumen}

{l s=' % Loaded'}

 

d'ont show me 0 % Loaded.

 

Does anyone kwons what happens,

 

Thanks.
