Problem with finding similar numbers in 2 columns in vba - excel

Question

i have problem with my code in vba. I have to find how much similar numbers are in column 1 and 2, but for example Column 1 (6,6,34,21,23,40) and column2 (49,34,6,9,6,20) should write 3 cause there are pairs 6-6, 6-6 and 34-34. I know its messy explenation but i hope its understandable. My code so far is:
Sub totolotek()
Dim i As Integer
Dim x As Integer
Dim j As Integer
Dim liczba As Integer
Dim suma As Integer
Dim ileLosowan As Integer
Range("B2:C7").Interior.Color = RGB(135, 134, 125)
Range("B2:B7").Font.ColorIndex = 3
Range("C2:C7").Font.ColorIndex = 5
ileLosowan = 7
Randomize
For i = 2 To ileLosowan
x = Int(Rnd * (49) + 1)
Range("c" & i) = x
Next i
For i = 2 To 7
liczba = Range("c" & i)
For j = 2 To 7
liczbe = Range("b" & j)
If liczbe = liczba Then
Range("c" & i).Interior.Color = RGB(255, 255, 0)
Range("b" & j).Interior.Color = RGB(255, 255, 0)
suma = suma + 1
End If
Next j
Next i
Range("c" & 9) = suma
End Sub

Answer 1

Try this. I invested some time and I added some lines of code. The macro find all the number pairs.
Example (6,6,3,4,2) (2,3,6,9,0) --> results 3: (6-6, 3-3, 2-2)
Sub totolotek()
Dim i As Integer
Dim x As Integer
Dim j As Integer
Dim liczba As Integer
Dim suma As Integer
Dim ileLosowan As Integer
Dim str_B As String, str_C As String, str_BC As String
Dim max_rand As Long
ileLosowan = 20 ' you can change the number of element in the column
max_rand = 49 ' max randum number
start_row = 2 'start_row
str_BC = "B2:C" & ileLosowan
str_B = "B2:B" & ileLosowan
str_C = "C2:C" & ileLosowan
Range(str_BC).Interior.Color = RGB(135, 134, 125)
Range(str_B).Font.ColorIndex = 5
Range(str_C).Font.ColorIndex = 5
Randomize
For i = start_row To ileLosowan
x = Int(Rnd * (max_rand) + 1)
Range("C" & i) = x
Next i
For i = start_row To ileLosowan
x = Int(Rnd * (max_rand) + 1)
Range("B" & i) = x
Next i
liczba_array = Range("B" & start_row & ":B" & ileLosowan).Value2
liczbe_array = Range("C" & start_row & ":C" & ileLosowan).Value2
ReDim ID_array(1 To 1)
ID_array(1) = max_rand + 1
Count = 1
For i = 1 To UBound(liczba_array, 1)
For j = 1 To UBound(liczbe_array, 1)
For k = 1 To UBound(ID_array, 1)
If ID_array(k) = j Then
GoTo out
End If
Next k
If liczba_array(i, 1) = liczbe_array(j, 1) Then
Range("B" & (start_row + i - 1)).Interior.Color = RGB(150 + Count * 20, 0, 0)
Range("C" & (start_row + j - 1)).Interior.Color = RGB(150 + Count * 20, 0, 0)
suma = suma + 1
ID_array(Count) = j
Count = Count + 1
ReDim Preserve ID_array(1 To Count)
Exit For
End If
Next j
out:
Next i
Range("C" & ileLosowan + 2) = suma
End Sub

Something like this will do what you're after. Just incorporate it into you're code cause I don't really know what's going on there.
Dim i As Long, j As Long, arr As Variant, Total As Integer
For i = 2 To 7 'Rows to loop through in the column
Total = 0
arr = Split(Range("A" & i), ",") 'Split column A using the comma
For j = 0 To UBound(arr) 'Loop through the split values
If InStr(Range("B" & i), arr(j)) > 0 Then 'Find if value is within other column
Total = Total + 1 'If it is, add 1 to total
End If
Next j
Range("C" & i) = Total 'Write total to another column on same row
Next i
Or if you want a basic function for it that you can use in your sheet you can use this:
Public Function CountMatches(Cell As String, Rng As Range, Optional Delim As String)
Dim i As Long, j As Long, arr As Variant, Total As Integer
If Delim = "" Then Delim = ","
If Rng.Count > 1 Then
CountMatches = "Please choose 1 cell to compare to."
Exit Function
End If
Total = 0
arr = Split(Cell, Delim) 'Split column A using the comma
For j = 0 To UBound(arr) 'Loop through the split values
If InStr(Rng, arr(j)) > 0 Then 'Find if value is within other column
Total = Total + 1 'If it is, add 1 to total
End If
Next j
CountMatches = Total
End Function
Use it like =CountMatches(A1,B1,",")
