I am trying to make a fillable form that allows people to put numbers in a few of the fillable spaces and calculate a number for them. I have used one before, but am not sure how to make one for myself. It is mostly simple addition and subtraction that needs to be calculated, but I am not sure how to create fillable forms which allow you to do this.
For example, if I want to calculate some dimensions for them, is there any way for them to fill in three different areas to get a total width of X.
Calculations are not something that FormsCentral currently supports in our forms.
