I have a billing database created with Filemaker, and I need to add the following functions:
* Now, each invoice currently consists of 3 amounts: Price / tax / Total (price + tax)
- Crerar field that adds the total of "Price" of: January + February + March = xxx / April + May + June = xxx / July + August + Setiempre = xxx / October + November + December = xxx
- Create field that calculates the same as the previous one but of the fields "Taxes"
- Create field that calculates the same as the previous one but fields "Total"
* Each invoice is associated with a customer, and I have a database of my clients
- For each customer, calculate the total invoiced during the last 12 months
Note: no database will be sended (private content), you must writte step by step what I must do, or chat
I can provide a copy of complet database witout real data
