Hello all. I'm having a very difficult time with javascript on a transportation site that I'm setting up. The form can be found at http://www.exitexpress.com/Reservations.htm. my problem is that I don't know how to do calculations. I need to be able to double the price if a person wants to make a round trip reservation. I also need to multiply the reservation price times the number of passengers. for instance, if the trip is 25.00 from one zip code to the next, the price will be 50.00 for 2 passengers, 75.00 for 3 and so on. Plus the round trip calculation. Can anyone help me with this? I would REALLY appreciate it. Thanks for your time in advance.

I guess you're saying you need a basic calculator. You can probably find what you are looking for here. www.hotscripts.com

Thanx for the expedient reply Dave but actually that's not what I'm looking for at all. I'm looking for a way to actually do calculations thru the actual form that's on that page I put up in the original post. Using javascript and variables. It's an eCommerce thing.

IMO the best way to do that is to use variables and IfElse conditional statements. I would suggest you read this javascript tutorial where it covers variables and conditionals. http://www.w3schools.com/js/default.asp
