Unfortunately, doing mathematical calculation will not be possible.
I've got a form that would also benefit greatly from some calculations (got a few total columns that it would be nice to auto fill based on user input in prior cells). Very happy to embed and take advantage of any extra code you're able to provide.
Look forward to hearing from you,
Hi Andi, we do understand your question is related and appears to be a feature request so I would like to kindly ask that you please open up this up as a New Thread Question with your details about what you are in need of. However, as stated at the moment we do not provide the ability to support advanced mathematical calculations on forms though it might possibly be able to create a workaround using the form's source code and some custom programming for now.
