Calculate price by length of name in custom field.

Is there any documentation how to setup this up... add a price for each character added in the custome field !!

Hi,

There is no documentation as there is no feature to do that. As we said from the beginning of this thread, it requires the development of a small price calculation override in order to handle that.
I invite you to contact our partners for a quote on such development if you're not a developer:
