In the step 2 (payment) of checkout I have the following table:

PHP Code:
Your Total
€40.04
Sub-Total:

€4.50
Zone Rates (Shipping to SI):

€6.67
:

€44.54
Total: 
The problem is that the "ottax" fild is empty, it's show only 6,67€ and there is no explanation of what is that ammount. I would like the text to show: 20% of tax

I had set up a tax of 20%


Thank's in advance!
