106795 PHP Calculator

This should be a very easy task for a good PHP coder. I need a calculator. It has a number of different sub-calculations and then needs to total all items. Results need to be presented on a a results page (see "[login to view URL]"), which is separate from the input form page ([login to view URL]). All the pulldown menus are shown on the [login to view URL] page. Math formulas have been worked out and shown both in comments as well as the table on the [login to view URL] page. You don't need to worry about any formatting, just follow the table on results.php. Use comma separator for thousands, no decimals.
