Do we have formula field type which uses other form fields to calculate.Asked by Ray on April 10, 2013 at 08:08 AM
Unfortunately, the calculation functionality is unavailable. As a workaround you can use the form's source code to do your calculation.
If your form is ready and want us to implement this workaround for you, we will be more than happy to help you on that.
