Additional charges for items based on custom field

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.3.1

We rent out bouncers that are wet. When customers want us to set up on dirt, we charge an additional fee. This is only for bouncers that are being rented wet and are going on certain surfaces, such as dirt, gravel (anything not pavement). The surface is a custom field. How do I set this up?

Hi,

If the customer's selection is to change the price, a custom field won't be of help.

For your case you may want to look into using "Options" for the surfaces: www.hikashop.com/support/documentation/i...ct-form.html#options
Different surface = different cost, and if selected as option it'll add the cost of it.
