What is the best way to add an estimate optionto my site. I dont really see any options and theres no way to do it through the native form builder. Im using Wix Studio I have an interior design business where I want a potential client to enter their square footage and the calculator multiplies it by a certain number to get a price Ive already tried the native form builder but theres no option for it I would like it to only givd the answer when a email is input ---

have you looked at the apps - this may help…or as codequeen stated it will need to be custom coded. > **[Calculator Builder | Wix App Market | Wix.com](https://www.wix.com/app-market/calculator-builder)** > > Add a customizable calculator to your site!
