Automatic Calculation

Please please please add a feature so that in the form a price can be automatically calculated when users select certain options.

We don’t need a pretty interface to make the equations easy to set up. We just need to be able to assign values to different fields and then (like with Calculated Fields Forms) to be able to write equations using the different fields as variables.

Thank you very much.
