hi. i got a task to do, and i have to use [u][b]LAMP[/b][/u]. I am slightly confused on the way it has to get implemented. all i need is some guidance (not the code). here is the problem. i got a database of 60 users with their contact details, and there is an extra column that is manually assigned a letter A, B, or C to the user. Depending on which area is coming from, it gets a letter. A for North, Bfor east, and C for south. week 1: Mon to Friday each day is gonna have one person from team A Saturday and Sunday each day is gonna have one person from team B and one from C. week 2: Mon to Friday each day is gonna have one person from team B Saturday and Sunday each day is gonna have one person from team A and one from C. week 3 Mon to Friday each day is gonna have one person from team C Saturday and Sunday each day is gonna have one person from team A and one from B. and the story continues. have in mind that i do not want a user from a team to appear twice, unless everybody from its team have done the job. for example user A1 cannot appear again unless all users A1-A20 have not done their job. any ideas? ???
