Sub-Total Not Calculating

[JewelryFromMyMind]

Sub-Total is not calculating on the checkout_confirmation.php page.

 

The item(s) in the shopping cart are listed, along with their individual prices, however, the subtotal remains $0.00. The shipping cost calculates, and from there, the Total only includes the cost from the shipping, as the items subtotal is $0.00. This total of only the shipping cost is passed onto paypal for payment.

 

Shipping method is USPS flat rate module, Payment method is Paypal module, however, the problem still exists even if these modules are changed.

 

On the shopping_cart.php page, and the shopping cart box, the Sub-Total calculates. For a reason I cannot figure out, the sub-total is lost/not calculating when it comes to the checkout_confirmation.php page.

 

I have installed the Purchase Without Account contribution, but after restoring the confirmation page, the Sub-Total still does not calculate, so i suspect this contribution is not the problem. Also, whether I am checking out with or without an account, the same problem occurs with the sub-total. I have previously installed a contribution that allows a product to be shown as "sold out" instead of listing a price. I unfortunately did not document this contribution.

 

I would really appreciate any help. Let me know if there is a segment of code I should post for review. Thank you!
