OK, to add onto previous question:

http://www.experts-exchange.com/Programming/Programming_Languages/Delphi/Q_20968246.html

i think this design will work, but it will take some re-working of my existing application, any suggesions:

I will then post a question for SQL statements need to calculate points.

Thanx!

Shane

I think the fields Team1 and Team2 in the table Matches double the field Team in the table MatchResults:

Teams
- id
- Name
- Points - Calculated

Players
- id
- TeamId
- Name  
- Points - Calculated

Matches
- id
- Date

MatchResults
- id
- MatchId
- TeamId
- Points - Calculated Field

Games
 - Id
 - MatchId
 - MatchType - {Singles, Doubles}

GameResults
 - Id
 - GamesId
 - Player - Selected from Players
 - Points (not calculated)

Q_20971121.zip
Really I don't understand what happens with my yahoo web-pages. I can access them without problems, but you are the first, who alert me for "currently unavailable for viewing" message, but already is another who alert me about the same ????
These web-sites belong to me, but I don't know what to do for avoiding this problem.
