Can't find why my code crashes

Question

I wrote this code to compare between A and B columns and whenever I have similar values like if the column A = B then show A, B, and C in E,F, and G like in the picture below :

This is the code I am using:

Option Explicit

Sub Comparatif_Release()
Dim t1, t2, c
Dim d As Object
Dim i&, j&, l&
Dim f As Worksheet
Range("e1:g110000").Select
Selection.ClearContents

Set f = Sheets("Sheet1")
With f

    t1 = .Range("a1:a10000").Value
    t2 = .Range("b1:c10000").Value
End With

Set d = CreateObject("Scripting.Dictionary")
For i = LBound(t1) To UBound(t1)
For j = LBound(t2) To UBound(t2)
    If t1(i, 1) = t2(j, 1) Then
        d(t1(i, 1) & ":" & t2(j, 1) & ":" & t2(j, 2)) = d(t1(i, 1) & ":" & t2(j, 1) & ":" & t2(j, 2))

    End If
Next j
Next i

With f
    i = 1
    For Each c In d.Keys
        .Cells(i, "E").Resize(, 3).Value = Split(c, ":")

        i = i + 1
    Next c
End With

End Sub

Answer 1

Use these formula and just filter them down. It should work. Late post, but just in case.

In column E1 :  =IF(A1=B1,A1,"")
In column F1 :  =IF(E1<>"",B1,"")
In Column G1 :  =If(E1<>"",C1,"")

A simple VBA version would be:

Private Sub CommandButton1_Click()
Dim i As Long
lastrow = Sheet1.Range("a1048575").End(xlUp).Row
For i = 1 To lastrow
    If Sheet1.Cells(i, 2) = Sheet1.Cells(i, 1) Then
        Sheet1.Cells(i, 4) = Sheet1.Cells(i, 1)
        Sheet1.Cells(i, 5) = Sheet1.Cells(i, 2)
        Sheet1.Cells(i, 6) = Sheet1.Cells(i, 3)
    End If
Next
End Sub

What about this part when you say then d()=d() ? Where both keys are seemingly the same and might not exist?

Full quote is:

If t1(i, 1) = t2(j, 1) Then d(t1(i, 1) & ":" & t2(j, 1) & ":" & t2(j, 2)) = d(t1(i, 1) & ":" & t2(j, 1) & ":" & t2(j, 2))
