Hi, what he needs is when a customer visits his online store, one of two things happen.
- for the ordinary folks visiting - they have to pay the vat (tax) on the product.
- for the school that places an order on his website - the vat (tax) is taken off at the checkout.
A bit like a select case statement
if A is picked - that is the vat
if B is picked - that vat is taken off…
