LCase & Fehler beim kompilieren

Sub OrtSuchen()
Dim lng As Long
Dim i As Integer
Application.ScreenUpdating = False
With UserForm3
.ListBox1.Clear
Sheets("DATEN").Activate
i = 0
For lng = 3 To ActiveSheet.UsedRange.Rows.Count
If InStr(LCase(Cells(lng, 7).Value), LCase(.TextBox7.Value)) > 0 Then
.ListBox1.AddItem Cells(lng, 1).Value
.ListBox1.Column(1, i) = Cells(lng, 2).Value
.ListBox1.Column(2, i) = Cells(lng, 3).Value
.ListBox1.Column(3, i) = Cells(lng, 4).Value
.ListBox1.Column(4, i) = Cells(lng, 5).Value
.ListBox1.Column(5, i) = Cells(lng, 6).Row
i = i + 1
Else
End If
Next lng
End With
Application.ScreenUpdating = True
End Sub

Wobei immer der das "erste" LCase in If InStr(LCase(Cells(lng, 7).Value), LCase(.TextBox7.Value)) > 0 Then angemarkt wird.
Was läuft schief?
