- Why have you chosen to use 3 files for this? Couldn't you just
- calculate the costs within the file that contains the orders? This could
- possibly make your life a little easier.

- Actually, what you want to use are lookup fields. These fields
- perform the function you are looking for, but they are not live direct
- links between the files. If you have some prices in the file already
- calculated, and then that price changes in the product file (which is
- where I'm assuming you have the product prices stored) you will have to
- tell the lookup fields in the other file that use that product's price
- to go and get the current price.
