Applying random discount off total price and adding set GST (TAX rate) to final total
Hi there just need some help as I'm very very fresh at using Adobe so I'm trying to learn as i go
So i cannot work out how to apply random discounts that will subtract automatically from my unit total. Going into the setting and changing to percentage does nothing except subtract 15 off the total price
The same thing applies to the GST (tax) here in my country NZ at 15%, then adding this to the grand total.
Any help would be appreciated
