Stacks Image 210937


Create custom formulas to calculate useful values. Almost anything that can be done with math can be calculated. With the Formula Stack you can give your users as many fields as necessary to gather any important variables and it will output a total value instantaneously. Provide quotes, calculate materials needed, total product cost based on selectable options or anything else that relies on numbers.

Exporting Values

The Formula Stack can also integrate with any form that uses input fields. Each part of the Calculator the user fills in can be automatically sent to a form Stack (Super Forms or any other 3rd party form Stack) so the information can be saved or used. In this example the dates, amount of visitors, and the amount of days is automatically added to the Super Forms Stack as they are filled out.

Super Forms has also recently been updated to support disabled fields so that the values cannot be changed once they have been exported to the form. Additionally, we have added support for hidden fields so that the values can be stored without displaying them in the form to the user.
