If you have created an item options Store Tag, and the item options selected are not being carried to the shopping cart, first, make sure that the option tags are formatted properly. After you confirm that they are formatted properly you also need to make sure that they are contained within the form. Here is an example of what an item with options tag code should look like:

<form method="post" action="<!--#ystore_order id="item-id" -->">
          <!--#ystore_catalog id="item-id" field="options" format="html" -->
      <input type="submit" value="Order">
      <input type="hidden" name="vwitem" value="item-id">
</form>
