I've seen in the documents that you can wrap
<span class="store_product_price"></span> around the price to make it dynamic. However, I absolutely cannot get this to work. It will display the starting price but will not update the price after you choose a modifier with a price adjustment.
I've also tested this in the store_example templates by wrapping the same span tag around the price list on the product template.
Is there something I am missing to make this work?
