How to calculate values on the fly

Let's say there are three fields on the add/edit page: Price, Quantity and Total. To calculate total value on the fly use Javascript code (add it to the Add page: JavaScript OnLoad event or Edit page: JavaScript OnLoadevent on the Events tab). Note: Change the values listed in red to match your specific needs. var ctrlPrice = Runner.getControl(pageid, 'Price'); var ctrlQuantity = Runner.getControl(pageid, 'Quantity'); var ctrlTotal = Runner.getControl(pageid, 'Total'); function func() {   ctrlTotal.setValue(Number(ctrlPrice.getValue()) * Number(ctrlQuantity.getValue())); }; ctrlPrice.on('keyup', func); ctrlQuantity.on('keyup', func); See also · Javascript API LINK :  calculate_values_on_the_fly
