Quantity Discount with Number Input

You can use the actual number entered by the user enters and the range-based value set by you in your calculations through a single number input element.

Use the element name directly in the formula for retrieving the range-based value, and type element name[actualvalue] in the formula to get the actual value entered by the user.


The most common use case of the above feature is Quantity Discounts. You can let the user enter the desired quantity and calculate the price based on the quantity-range value set by you in the element properties.

As shown in the image below, you can set different prices for different quantity ranges, $5 for range 1 to 49, $4 for range 50 - 99, and so on.

Then, in the formula, you can retrieve the quantity-based price through the label name, i.e. "Quantity", and the actual value entered by the user in the number input through "Quantity[actualvalue]". So, the final price can be calculated by the formula - Quantity*Quantity[actualvalue]
