Hi All

I am need of having another column in my quotes. My calculation is not as simple as item quantity x price. We hire equipment out per day so we need to calculate item quantity x price x days. For e.g.

Customers could hire 5 power drills at $10 each for 2 days - They should pay $100. So my quote / sales order line would look more like this: 

Product            Quantity            Period           Price                    Total

Power Drill -     x units (5)         x days (2)     x price ($10) =     $100

How can I do this?
