Formscentral forms do not support field calculations at this time. It is a feature that has been requested and you can vote for it on our request list if you haven't already done so.
Yes, this is quite a large weakness in the current feature set.
i need this feature too, where can i vote for it ? What i need exactly is the ability to calculate with excel formulas likesay
Daily Power Consumption is SUM=(E1:E25) with E1 to E25 = (B1 x C1 x D1)
B1 is the wattage per home appliance
C1 is the number of appliances used,
and D1 is the number of hours this appliance is used per day
(Wattage × number of appliances x Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption
1 kilowatt (kW) = 1,000 Watts
(1800 Watts × 2 clothes Iron x 2 hours/day) ÷ 1000
= 7.2 kWh
Personal Computer and Monitor:
[(120 Watts + 150 Watts) × 2 pc x 8 hours/day ] ÷ 1000
total would be by adding all applicances: 7.2 kWh + 4.32 kWh ect.... and my visitor online would only sees the final answer like you need 20 kWh on daily basis.
now Drewy answered on this link http://forums.adobe.com/message/5056250#5056250 that it is possible to make calculations on Adobe XI and host them here with Forms central. what i'm asking you here, is does Adobe XI support what i need, does it have all formulas i just mentioned ? can i get a demo before purchasing ?
I would also appreciate you email me to email@example.com your answer/ feedback
