net price in invoice

hi,

in my vte installation, when i select "individual" tax calculation in invoice module the net price is equal to total price... this is not right! it's a bug of the software or my problem?

thx

I modify the function that calculate the total of the invoice (quotes, orders ecc.. ecc..) to resolve this issue, attached here is the inventory.js to substitute in the "include/js" folder (if you want to try, make a backup first...)
