I was wrong - that doesn't work
Unfortunately my "solution" is not working trough the whole process!
Although it is shown now the correct value as Grand Total on the cart-, confirm- and checkout_success-pages, because I display the "TaxableTotal" instead of the real Grand Total ...
The problem is that the real Grand Total value is further used under the surface.
It is inserted as the OrderAmount in the database and is also submitted to PayPal and thatswhy will be charched from the costumer.
So, instead trying to change that, I think it's more easy going back to my first idea and trying to solve the issue in that way ...
So, I think the questions are:
Where and how will the Grand Total be calculated ? and
Is it possible to distract the calculated tax from the Grand Total and how ?
Many thanks for any help on this!
Maybe there is also another solution to accomplish that ... (?)
It would be great if I could get an advice here!
PS: If anybody could post back soon, this would be highly appreciated.
Because I am starting to run out of time for that project...
