    How can i protect a field?

    Asked by Jonty on April 16, 2014 at 06:29 AM


    I'm doing a calculation which combines frequency of payment (monthly, weekly) with an amount input by the user, to generate an annual figure. How do protect the result (annual) field to stop users entering data into it?

    Any help would be very welcome.

    Thanks in advance,

    Hi Jonty,

    Open the calculation wizard on your annual field by clicking the magic wand icon. Make sure to add the formula (it seems like you're using the old calculation feature so I think you have to update the formula on your annual field if it's blank). And then check the "Read Only" option once done so the field can't be edited on the live view.

    Hope this helps. Thank you!
