A script to add a 100% discount on dishes of a certain category, if there is a dish with the code «N»
When a dish with the code «N» is added to a new order, a 100% discount is assigned to dishes of a certain category. If a dish with the «N» code is deleted, the free dishes are deleted as well.
On the receipt editing form of the CheckView object, insert the following script in the CurItemChanged event:
