How do I make prices not a preset value, rather a custom value that is subject to change?

How do I make prices not a preset value, rather a custom value that is subject to change?

I am trying to let users be able to set their own prices when they create a new order using the Order Management database for Zoho Creator.

As of now, the price section is grayed out when I try to create a new order. Since we are a wholesale company, I want this to be a custom price that is subject to change depending on the volume of the order.
