Price based on dimensions (per square meter)

[frankkubiak]

I am trying to set up a shop with custom made products.

Customers should be able to enter dimensions like length and width. The price depends on length * width (i.e. per square meter).

Is there a way to accomplish this with attributes? It would be ok, to use drop-down fields for entering the measurements.

My problem is, that I only found a way to calculate based on the product price and no way to calculate based on the total including attribute-price.

Example:
[FONT="Courier New"]
Product: 10 €
Length: 3 m (+ 20 €)
Width: 3 m (+20 €)
----------------------
wrong price: 50 €
[/FONT]

Should be:
[FONT="Courier New"]
Product: 10 € / sqm
Length: 3 m (* 3)
Width: 3 m (* 3)
------------------
right price: 90 €
[/FONT]
