Cognito-forms – How to send a confirmation email to an email address inside a repeating section in Cognito Forms

There are a couple of ways to handle calculating subtotals for repeating sections:

1. If the form represents a true invoice and the subtotals represent money and nothing else, you can set the form up to use the built in payment features of Cognito Forms. When you mark fields as Collect Payment, they will automatically appear on receipt/invoice grouped by repeating section item. Choice, Currency, Yes/No and Price fields can all appear on this "invoice" and the Price field gives you complete control with the ability to calculate both the amounts and the description of each line item if you need this power. In this case you would not be collecting payment from them, so mark the form via Payment Settings as never requiring payment.

2. The other option is to use the powerful calculation capabilities in Cognito Forms to quickly calculate the subtotals. In the example above, you could add a Calculation field at the bottom of the form and use a calculation like =MyOrder.Sum(ItemTotal) or even =MyOrder.Sum(Product_Amount * Quantity) to calculate the total for the My Order repeating section. Remember set the Type to Currency for the Calculation field so it will be formatted correctly and allow you to use the value of this field in other calculations. You can learn more about these capabilities in our help documentation at: https://www.cognitoforms.com/support/51/calculations/repeating-sectionstables. Take a look at the section on Working with Repeating Sections.

There are a couple of ways to handle this in Cognito Forms:

1. Include the camper registration fee of $60 for each camper as part of the repeating section. Then add a Price field for the multi-camper discount below the repeating section, using a calculation like =Campers.Count() > 1 ? (Campers.Count() - 1) * -30 : 0. You can hide this Price field or make it only appear when the discount is not zero. This would produce a receipt like:

   Camper 1   
       James Philips        $60.00 
   Camper 2   
       John Cartin          $60.00 
   Camper 3 
       Parker Owens         $60.00
   Multi-Camper Discount   ($60.00)
   --------------------------------
   Subtotal                $120.00
   

2. You could also charge $30 for each camper and have a separate $30 registration fee that applies to each application. I definitely prefer the first option since it clearly identifies the discount on the receipt.

Long term, it sounds like you would benefit from being able to use the Index of the item in the repeating section within calculations. We are looking at ways to make additional information like this available to calculations. In the mean time, hopefully these suggestions will meet your needs.
