You have chosen to sponsor your bid up to a maximum amount of .
I want to be able to sell a product by length and i want to keep the quantity field.
The customer will enter desired length and it will have impact on the price.
The impact value will be different on each product.
I want the price to automatically change while typing in the text box.
Product fixed price + ( "Entered Length" x Attribute(price impact) )
The solution have to be bug free and work all the way from product page to back office...
