I love this extension and have used it at my personal ecommerce site for some months. It monitors the product options, lists quantity for each option (or "out of stock") and updates the product's base price instantly depending on whether options that are selected increase or decrease the base price. It disables the Add to Cart button (putting the text Out of Stock there instead). It worked excellently in OC 1.5 last year, but there seems to be an issue with my new installation of OC 2 this year.
When all the options are out of stock, the base price of the product is listed as $NaN.N -- Here is an example screenshot, for a product that has a base price set in the OC 2 admin of $22.00--

Anyone else see this issue?
Thank you.

UPDATE (March 16, 2015)
This problem is apparently the result of a conflict between two extensions, both of which I like very much, Live Price Options Pro and Sold Out Label, a new OC2 extension by developer opencartboost--

I hate to choose between the two extensions, but for practical reasons at my store I need Live Price Options Pro and its functionality more than I need the Sold Out Label functionality. I sell products only by option (the base product is just a generic representation of the item, which only exists in its various options) so I really need the functionality of Live Price Options Pro, for which I'm very grateful to the developer, flanders.
