I would like to have something like this, where AnnualSales is automatically populated with the sum of the four quarter sales figures:
Q1Sales Q2Sales Q3Sales Q4Sales AnnualSales
------- ------- ------- ------- -----------
123.12 234.23 345.34 456.45 =sum(Q1Sales, Q2Sales, Q3Sales, Q4Sales)
Is this possible with OOTB functionality, or must I find another way of achieving this?
