You have chosen to sponsor your bid up to a maximum amount of .
We have an installation on joomla 2.5 and virtuemart 2.2. We need to develop, for some product, the possibilities for customer to enter lenght and height and choose an attribute from a dropdown menù.
The price will be calculate with this formula:
TOTAL PRICE= lenght * height * price of object (that is price per square meters). The attribute from dropdown menù just add a fix difference of price.
I can send a mok-up and a "live demo" from a other site.
The developer will get the password to install the plugin in the shop.
