This is a easy modification that I need done for OsCommerce add-on. This is an urgent work and I need it to be done in a day. It souldn't take more than an hour for someone with knowledge on oscommerce and php.

I am working on a automobile website and there is an add-on for oscommerce (http://addons.oscommerce.com/info/6684) that displays make model and year. What I need is as follows.

I need the addon modified to include engine as well. That is the add on will offer make, model, year and engine instead of just make, model and year as it does now.

Also it needs to be arranges as Year, Make, Model and Engine. That is first the visitor will select year from a list box, this will populate the Make list box with all makes under that year, then visitor will select Make from make list box, this will populate all Model under that specific make, visitor will select model, this will populate all engine under that model. Visitors will finally select engine, and this will bring all product under that engine.

Very simple work. I am not hardcore with php else I could ve done it myself.

To sumup, you need to replace the dropdown with list boxes, add another field 'Engine' and arrange it as Year, Make, Model, Engine.

I need this done rightaway. Successful person is in for a good review.

I am hoping to select a programmer right away so if you are up to it, bid now. Work must be complete within 24 hours. Payment via paypal on successful completion of work. Ok here is an addition. I need something similar to this http://parts-catalog.acdelco.com/b2c/catalog_search.php
