[mike2]

Hi...
When im adding some code, all of the other code stops working
Here's the code:

If Left$(strData, 9) = "USERLOGIN" Then
        strArray2 = Split(strData, vbCrLf)
        If ReadINI(App.Path & "\users.ini", Right$(strArray2(1), Len(strArray2(1)) - 13), "Password", vbNullString, 100) = Right$(strArray2(2), Len(strArray2(2)) - 13) Then
            '<:-) :WARNING: Empty String assignment updated to use vbNullString
            '<:-) :PREVIOUS CODE : If ReadINI(App.Path & "\users.ini", Right$(strArray2(1), Len(strArray2(1)) - 13), "Password", "", 100) = Right$(strArray2(2), Len(strArray2(2)) - 13) Then
            If ReadINI(App.Path & "\users.ini", Right$(strArray2(1), Len(strArray2(1)) - 13), "Banned", vbNullString, 100) = "True" Then
                '<:-) :WARNING: Empty String assignment updated to use vbNullString
                '<:-) :PREVIOUS CODE : If ReadINI(App.Path & "\users.ini", Right$(strArray2(1), Len(strArray2(1)) - 13), "Banned", "", 100) = "True" Then
                sckIntro(Index).SendData "BANNED"
                Exit Sub
            End If
            If lstUsers.ListCount < 20 Then
              sckIntro(Index).SendData "FULL"
              Exit Sub
            End If
          
       [b]     Dim i As Integer
            For i = 0 To lstUsers.ListCount - 1
            lstUsers.ListIndex = i
            If lstUsers.Text = Right$(strArray2(1), Len(strArray2(1)) - 13) Then
            sckIntro(Index).SendData "ALREADYLOGGEDIN"
            Exit Sub
            Next i
            End If[/b]
            
            sckIntro(Index).SendData "GOODLOGIN"
            lstActions.AddItem "[" & Format$(Time, "hh:mm:ss") & "] " & Right$(strArray2(1), Len(strArray2(1)) - 13) & " has connected."
            AddHScroll lstActions
         Else 'NOT READINI(APP.PATH...
            sckIntro(Index).SendData "BADLOGIN"
            lstActions.AddItem "[" & Format$(Time, "hh:mm:ss") & "] Someone tried to login with a bad username or password!"
            AddHScroll lstActions
        End If
    End If

The code works fine without the bolded part...
When i add it, the code stops working and its giving errors!
What should i do?

Thanks!
