HI ,

need help trying to create the folloiwng on quotes, and invoices.

We sell Tiles,, and we sell them by Boxes, Now each item boxes quantity is different in terms on square meter coverage per box.

As we sell by box.. we want to show the total number of square meters that total boxes would cover. We have included a field in items, showing the number the Meter square in a box.... and ofcourse the total boxes purchased or requested is also showing in the Quote, invoice, etc....

What is the best way to do this.

example..... 40 boxes (purchase) each box contains 1.42 square meter.... total square meter 56.80 square meter
