Hi Russell,

right, I wrote it manually. Thanks for your formula, the problem I have is that 
there
could be an "item 3" and therefore the "sum", "tax" and second "sum" lines are 
not fixed.
Is there a solution to specify them dynamically or do I have to modify the 
position
every time I enter a new item ?

Thanks,
Martin
