[Plugin: WP e-Commerce] Problem with Total Price

I’m having a problem with the order total mechanism.

Using WP 2.6.3, wp-e-commerce 3.6.8 rc3, clean install of both with no other plugins.

The problem is that in the checkout screen, the order total is not being properly calculated.

If only one shipping method is activated (Flat Rate, Table Rate, UPS, etc) the shipping WILL NOT be added to the order total.

If several methods are available, the Order Total will be updated using the shipping value at the top of the list. If you select a different shipping option the order total might be updated (I have tried countless variations and sometimes it works, sometimes it doesn’t). If it does happen to work, the Order Total will not update again if another shipping option is selected.

Sometimes, if you click the radio button that is already selected for your shipping option, it might calculate.

Additionally, Table Rate values do not calculate properly, sometimes working and sometimes just using the last value in the table regardless of total price.

Any help would be greatly appreciated! I’m sorry that the circumstances are rather vague, but I have spent hours trying various combinations and values, and have been unable to determine any pattern – the basic issue is that there seems to be a problem with the order total mechanism.

Thank You!
