Why field can't automatically calculate like 2+2?
I'm developing an inventory database. In real situation, when I count in warehouse, I need to note down some numbers first, then add more numbers. I just wonder why FM can't auto-calculate 2+2? I googled but failed to find an answer.Pls help. In Excel, it's so simple. I can't assign several field to each number because I feel that's the "stupid" way. For auto-calculation option, it asks for formulation between two fields. My issue is how to auto-calculated without fields like in Excel's cells. Thanks in advance. Kind of urgent!!
