When we are trying to indicate the date or order quantity, do we use "on" an order or "of" an order?
- Change the date on/of an order
- Update the order quantity on/of an order
Since the order quantity belongs to the order, shouldn't we use "of" instead of "on?" I often hear people use "on" over "of."
Can someone explain the difference between "of" and "on" and how each is used?
I know we can also say:
- An order of ten items.
- Ship date of 3/22
Please critique if any of the above is incorrect.
