EXCEL VBA , IF statement not working properly

By some unknown reason my If statement is not working properly i tried to invert the signals if seek of any improvement , but none so far. Leaving some of the code bellow.

For i = 1 To last
REFERENCIA = Application.ThisWorkbook.Worksheets("Registos").Cells(i, 8)
ENTRADAeSAIDA = Application.ThisWorkbook.Worksheets("Registos").Cells(i, 12)
CC = Application.ThisWorkbook.Worksheets("Registos").Cells(i, 6)

If REFERENCIA = registos.TextBox1 And registos.ComboBox1 = "SAÍDA" Then

     Worksheets("registos").Select
     ActiveSheet.ListObjects("Tabela1").Range.AutoFilter Field:=8, Criteria1:= _
     registos.TextBox1.Text                                                     'Filtrar referência

     ActiveSheet.ListObjects("Tabela1").Range.AutoFilter Field:=6, Criteria1:= _
     registos.Label11.Caption                                                                            'Filtrar CC


     ActiveSheet.ListObjects("Tabela1").Range.AutoFilter Field:=12, Criteria1:= _
    "ENTRADA"                                                                           'Filtrar Entrada

    'Somar quantidades de peças de Entrada
    xty100 = ThisWorkbook.Worksheets("calculos").Range("A1")


''       Worksheets("registos").Select
    ActiveSheet.ListObjects("Tabela1").Range.AutoFilter Field:=12, Criteria1:= _
    "SAÍDA"                                                                             'Filtrar Saída
    xty101 = ThisWorkbook.Worksheets("calculos").Range("A1")
'        'Somar quantidade de peças de saída

    sumfinal = xty100 - xty101
    xytbx4 = Format(registos.TextBox4, "@")

 If xytbx4 < sumfinal And xytbx4 > 0 Then
GoTo salto_2

Else
MsgBox "Não é possível movimentar mais que o stock atual!Stock " & sumfinal & ""
GoTo fim
End If
End If

Next i
