Updating the savings with options

When a product is a specific price for example $123.00 and the list price is $345.00, you can have PC show the savings line of a total $222.00 (see screen shot 1)

However when I have options with this product, and you select an option where it adds $11.00 to the price, the savings line is not updating.
Example: Price $123.00 + option $11.00 = $134.00
The list price remains $345.00
So calculating $345.00 - $134.00 = $211.00, yet is still shows $222.00 (see screen shot 2)

Is there an easy way to have this updated as well?

I haven't used the apparel add-on, but I just took a quick look at the info about it and I think it's a great match for your site.  I can't tell from the screenshots if your using it already, but if not then it's well worth a look.

If you compare selling a rug to selling, say, shirts then there are many similarities :-
- Come in a range of sizes and possibly colors.
- Each variation can have it's own stock level & SKU.
- Each color variation can have it's own picture.

Thanks for your reply Hamish,
I can see your point with that the reduction remains the same and therefore the savings line does not change...
So let me rephrase this question: How to have the reduction automatically adjust to the option selected?

I really would like to show the user what they will save from the total price...

About the add-ons for PC:
I have indeed the apparel add-on with it. (Great you thought of that!)
It works indeed great with sizes, colors, shapes, etc., that can be options for our rugs.
Perfect thing in PC is, that for out furniture section we do not have to use it...
Very satisfied with PC so far!

Hi - We posted at the same time :-)

The saving remains the same, they have added an option costing eleven dollars and they will pay you eleven dollars more, so the saving does not change at all.  

I think what's causing the confusion is the line reading "Price:"
This is really the "Price including Options".
The "List  Price" and "Savings"  are of the base product.  I can see it gives the incorrect, but it is just a matter of the wording of "Price". The maths is fine.
