How to Accept Payment with Quantity Calculation
On a form that accepts payments, it’s very common to have a quantity field to calculate the total price. Like this:
Add a price-enabled field
The first thing you’ll need to do to create such a form is add a price-enabled field to it. A price-enabled field is a field that can be associated with a price. These field types are price-enabled fields: Multiple Choice, Checkboxes, Drop-Down, and Price.
Add any of the above fields to your form by clicking the field button. In the above example, we’re adding a Multiple Choice field to our form.
Add a Number field
Next, add a Number field to your form, go to the field properties tab, and enable the ‘Enable as Quantity’ field option.
You can select the target field for the calculation. In this case, we would like to associate the Quantity field with the Which balloon you would like to purchase? field, so we selected the multiple choice field under the Calculate with this field dropdown.
Save the form, and that’s it. The total calculation will be displayed instantly as the user enters the quantity.
