MX Kart Forum :: discounted price not working

Using the offers_nug.php page to try to show a product price with a strike-thru and a discounted price next to it does not work for me.  I have a discounted price in the discountedprice_pdi field of the productdiscount_pdi table, I have the offer flag enabled in the products_prd table for the items with discounts, and the offers nugget shows the items that are being offered, but it doesn't show the discounted price.

In looking at the code that is generated using the "Show discounted Price" server behavior, it asks for the "Product Price', and the "Product Primary Key Value".  Also, the code shows the "product price" coming from the price_prd field of the products_prd table, and not the "discountedprice" field of the productdiscount_pdi table, so it only makes sense that it would show the original price.

I tried creating a new record set with the productdiscount_pdi table as its contents, and pointing the "Product Price" to the "discountedprice_pdi" field and it will then show a discounted price, but I can't figure out how to track the primary key of the item to be sure to show the correct discounted price from the productdiscount_pdi table.

In other words, I am trying to figure out a way for the idprd_pdi field of the productdiscount_pdi table to be set equal to the id_prd field of the products table to make sure that the discounted price matches with the correct product.

Anyone have any ideas?
