Questionhow to use temporary values Pin

Hi i have a mysql database which i use to update a soccer league table when i enter in results from a form, works fine, however i would like to be able to enter latest scores and update table based on latest scores entered but i cant work out how to do this as at the moment when i enter an update in the score for a match it will treat it as a new match and allocate points etc all over again

Example

teama 1 teamb 0 would give the following teama goals for 1, teamb goals for 0, goaldifference = teama goals for - teamb goals for which in thiscase would be 1

if it changed to

teama 3 teamb 0 would give the following teama goals for 3, teamb goals for 0, goaldifference = teama goals for - teamb goals for which in thiscase would be 3 but it adds the 3 from this update to the 1 from previous update giving 4.

so i need a way to stop it treating each update as a new result and only update with new data - the previous data so in my example

3 goals - 1 goal from first update = 2 goals , i have other fields like points that need to be treated same way.

hope someone can helpout with this and point me in right direction

kenny
