Create Webform

We need to create a webform that allows people to register for an event. It must have three uses: 1. Allow registrants to enter their name, email, street1, street2, city, state, and zip code. 2. Allow registrants to add guests (collecting the same information). 3. Calculate the total due for the event (price x people = total due). 4. Calculate a discount for all the people that have a membership number. 5. Charge a credit card via [login to view URL] using the class provided, and display a receipt or decline notice depending on the response. 6. Save all registration information (except credit card info) in a csv file in the same directory.
