Hello, I need some help. I have a computer order form in my website that I have created drop down fields for. EX: System Type: p41.7ghz($599) and other choices then on the other fields below it are upgrades that may be added to the system. I am trying to get the fields to add together and I am not sure how to assign the amounts in the drop down menu. I need a total to appear on the same page and then all the info from the fields chosen along with the total to pass to another page which they would enter their personal information and tax and shipping would be calculated. I am then going to pass the grand total to a service like Authorize.net
Thanks,
Neil
