If you are trying to advance from the cart to the check-out page, but the page seems to just refresh, then the most common issue is that the quantities you ordered did not divide evenly by the Case Pack. The Case Pack is a unique number for each item that describes how many pieces come in a full box of the item. We require all items to be ordered in increments of the Case Pack, and you cannot advance to checkout unless all quantities ordered divide evenly in to this number.
