    I really am struggling in wanting to use your service over others becuase I like your product better. But they have 2 critical features I need that you don't have presently.


    I need to be able to calculate fields. For example I need to take a value the user inputs into field #1 and have jotform use my rules to multiply that number by 0.85 then return that calculation value in field #2. I read some info on the forums on how the purchase order field can help. In this case It doesn't.


    Also, for the value that is returned in field #2, I don't want the user to be able to edit that value. It should be displayed (i.e. not hidden) so they can chose to accept the offer, but cannot be edited. It would make proessing payments very hard once the order is received to re-calculate that field if the user modified it. So it should be in a sense "grayed-out".


    Are you working on anything like this? If so, do you have an ETA for it? (even if just rought estimate, like a couple months, weeks, days?). If not, could you start working on something like this?

    Hi guelphlittletheatre and Zachary,

    Thank you very much for sharing your thoughts with us. This feature has actually long been requested by other JotForm users and is definitely something that's in our priority to do list. I'm not in the position to give an ETA since our programmers are the ones who can determine it. But they will definitely give you an update through our website or our Twitter account. Rest assured that your patience and long wait will be worth it.

    Please let us know if you have any other questions, concerns, or suggestions. Thank you for using JotForm!

    It's almost 2014!! Is this ever going to be available.  Would also be nice if it was an option in the Matrix.

    We already have the calculation feature. Unfortunately, matrix field is currently not supported. Please kindly create your own separate thread so we can assist you about this function. You can create a thread using this link: http://www.jotform.com/answers/answer.php?.
