how do I update 1 table from data in multiple tables?

[ICEcoffee]

Hi all

I am using dreamweaver 8 to build an Fantasy Formula 1, data driven website, but this is not a dreamweaver specific question.

I have data that has been entered into various tables depending on results of a race, and want to update a leaderboard table with the results.

I have a users team table, which includes fields for: user team name, driver1, driver2, chassis etc

What I want to do is create a page, so that the end of the race, when data has been entered into the various tabes: qualify_results, Race_results, retirment_results etc to check the entered data and if a user a chosen has chosen a driver that has been awarded points, those points are entered into a new row in the leaderboard table, with any other points/penalties as appropriate.

Is anyone clever enough to guide me through the PHP logic? I am a newbie (still) and any help would be appreciated.

Thanks
