I have just added some new products and I am trying to check the "Price Includes VAT" option but it is not letting me do it. I don't understand why this has happened as it did not say this before as I have existing products checked with this option, but trying to uncheck/check them throws this error too?
I have filled in the default option "Domestic" in the Sales & Receivables Setup like the default demo environment, however this still throws up the error?
