We have a simple webform that you enter in the following:
#of gallons (end user entered)
Less account credit (end user entered)
It then calculates #of gallons * the price 1.169 per gallon. It then multiplies sales tax of 6% (.06) and then subtracts the "Less Account Credit"
The total amount due which is generated by the above form and a form for gathering account#, first name, last name, address, city, state, phone, zip, email and then credit card number is entered and then should be passed to Authorize.net for processing. ... We need the web form to pass data to authorize.net and charge the credit card and then send an email to our sales team so they know an order came through.
