Change Include Scrtipt

Require a php script to ad an include file of additional information on a page when something is selected. An example is [login to view URL] - select 2006 Chevrolet Silverado and notice the options available midway down the page, now change selection and select 2004 Ford F150. You will notice what items changed for options to purchase. Also in the purchase “Select Model” the color selection isn’t available untill you select model and the ‘Add To Cart” button isn’t active until you select a color. We wish to achieve the same thing with a static page that will be named .php to allow an include to run and changing an include for the new information. Could be satisfied with just a single change for color selection as model type will be a static page.
