**achex**I'm just wondering if there is an option to do calculations using different fields on my form.

**jedcadorna**You might want use one of our payment tools to do the calculations. Please refer to this thread for additional info http://www.jotform.com/answers/92783-Can-I-do-calculations-in-my-forms-Also-can-I-get-values-formatted-at-money-115-00-.

Otherwise let us know the formula of the calculation that you want and we'll let you know if its feasible in the form builder, if not you have to download completely your source code and make some modification base on your calculation needs.

Thanks,
