Dovi... I think that is correct. The way that I think you've got this set up is that there are three tables: (.DBF files).

1. the Customer file. This includes their name/address, etc. and their RATE.

2. the Country file. This includes the country name, the dialing prefix

011 US
043 Austria
049 Germany

3. The calling records. These should include:

   a,) the dialed number from which you can find the country code<br>
   b,) something which identifies the customer<br>
   c,) the length of the call in seconds or minutes.<br> 

One problem I can see with this, is that it doesn't take into account differing rates at different times of the day. For example we might have Day rates of 40 cents per minute for in-state log distance calls, and Evening rates of 10 cents and Night rates of 2.5 cents. But, this should be a start.
