Tables i got are: Users, Machines, UsersMachines
Users contains: ID, Name, Email, UserGroupID,
Machines contains: ID, Name
UserMachines(relational table) ID, UserID, MachineID,
So now in a form first the machine is choosen & then it must be filtered in Users.
So it must display all users from choosen machine.
Thas all.. along with that i want UserGroupID to be choosen manually as UserGroupID IN (2,11) 2,11 are type of a user
