Hi All,

I have the following problem. (?)

The situation:
- a xustomer bought a gift certificate for example $5+tax, where the tax is 20%, so he have paid for $6.
- the buy a product, which has price also $5+tax ($6). The customer want to pay with the gv, but he can use only $5 instead of $6.

It seems, that there is double tax evaluating.

Could someone explain to me what's wrong?
