Is it possible to add order tag quantity?
I have just realized that the quantity is always 1 on all order tags so {ORDER TAG TOTAL PRICE} is wrong.
It is calculating the correct discount - see You saved €500 Totay!
I have overcome this by using [=F(TN('{ORDER TAG TOTAL PRICE}')*('{QUANTITY}'))]
But I’m wondering why tag quantity is displaying as 1 when it is actually correctly calculating discount as 10?
EDIT: Just found this post which explains everything.
