I would like to know if it is possible get a formula affected only on selections of one field.
i.e.
I´ve a table INVOICES with several fields (Dates, Customers, Amounts, Salesreps ...) in one sheet I have a list field on CUSTOMER with all of posible customers on invoices.
Is it possible create a text field with the sum INVOICES.AMOUNT for all the selected CUSTOMERS but without considering the rest of the selections.
With this data.
INVOICE,CUSTOMER,MONTH,AMOUNT
INV-1, CUST-1, JAN, 1000
INV-2, CUST-2, FEB, 2000
INV-3, CUST-1, MAR, 3000
INV-4, CUST-4, APR, 4000
The total amount would be:
Without selections = 10.000 (All of the invoices)
If JAN is selected = 10.000 (All of the invoices , there is not selections on CUSTOMER)
If select CUST-1 = 4000 (INV-1 + INV-3 are the invoices for CUST-1)
If select CUST-1 and JAN = 4000 (INV-1 + INV-3 are the invoices for CUST-1 without considering MONTH)
