I have checked your form 60902398728869, and it seems to be working fine or some products, while it is failing on others.

For example, selecting a "quantity" for product "SPAIN - Sagrada Familia, Beach Backpack Sunlight (ocean blue - sky blue)" will remain at the price for one product:

This is happening because you seem to have used a "Custom" property instead of the actual "Quantity" property for your products:

The built-in quantity property is the one that will allow the price to be calculated correctly, based on the number of items that are selected. The "Custom" property that is being used now, even though its name was entered as "Quantity" is still a custom property that cannot be calculated.

I would recommend simply removing your existing custom property from the product, and adding a regular quantity property instead. You can do this from the payment tool's wizard, by:

(1) clicking on a product,
(2) clicking on the X-shaped icon next to its custom property,
(3) clicking on the pencil-shaped icon to create a new property, select Quantity, then click Next
(4) clicking on Save Product

Please let us know how it goes.
