MySQL PHP Programmer

I need someone that knows mysql and php login scripts. I need someone that knows how to make numbers add up in mysql database. Example: 1 3 2 7 5 9 = 27 With this ... everytime I have someone log into my website through php login script that I have. It will keep "individual" track of each user that enters these numbers. I believe it called a unique identifier. So if Joe, Bob, and Harry where logged into my website. When they go to add their numbers, it will keep track of "each individual" member that logs in. I will give more details when you sign up. Thanks, Reco Deon!!!
