    Thanks for reply. I am not understood, your code, could u please little be elaborate?

      There is not a lot to it. What part of it is confusing?

      • The if statement? See if
      • The condition? That's just a flag that gives true if there are no other users logged in. Count the active logins to see what it should return.
      • Printing a normal page? Presumably you already do this.
      • Printing an error page? This is the same as a normal page, but with a different message.
