Excel VBA: Overflow error

Question

Just started programming in VBA, I have a problem, and i don't know how to solve this. I think everything is ok. There shows Run-Time Error '6' Overflow when i want to run this macro.

Sub Działaj()
Dim Tablica(1 To 5000) As String
Dim Dni()
Dim kolumna As Integer
Dim wiersz As Integer
Dim licznik As Integer
Dim PF As Boolean
Dim tmp As Integer
Dim i As Integer
Dim tmp2 As String
licznik = 2
tmp = 0
PF = False
kolumna = 22
wiersz = 2
Do
    If Worksheets("Początkowe").Cells(wiersz, kolumna).Value <> vbNullString Then
        For i = 1 To licznik
            If Worksheets("Początkowe").Cells(wiersz, kolumna).Value = Tablica(i) Then 'debugger shows problem here i guess
                PF = True
                tmp = i
            End If
        Next i
    End If
    If Worksheets("Początkowe").Cells(wiersz, kolumna).Value = "koniec" Then
        Exit Do
    End If
    wiersz = wiersz + 1
Loop
End Sub

Can anyone tell me where i made a mistake? I would be very grateful.

Answer 1

If you don't find the value koniec before row 32767, your variable wiersz will max out. If you want to continue past that, you should redefine it as Long.

You should also provide an exit for your loop, e.g. existing at the last used row. Instead of a do ... loop, I usually use the following code:

Dim lLastRow As Long, lWiersz As Long

lLastRow = Cells(Rows.Count, kolumna).End(xlUp).Row

For lWiersz= 1 To lLastRow


Next lWiersz
