Database script (ASP)

I'm working on a web based database project. I use ASP, Access and win 2000 (IIS 5). I Simply need a script to do the following: Users are in several groups. One is, for example in group A and the other is in group C. "One" wants to change group and become a member of group C. The system doesn't allow this UNLESS the "other" wants to change group too. The number of the members of the groups cannot be changed so the system only allows mutual changes. "you cannot change group unless there is a person who wants to go to your group" I hope this is helpful enough. The script must be running once a day...I also want automatic warnings to users participating in wrong groups (or not participate at all) as they login to the system. (I can check that). Example: A user is registered in group C but I realise that he participates (or had participated once) in group B ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
