I have a macro that works manually and with Ctrl + I, but when I put a button, the macro doesn't work.
Sub Duplicar()
'Updateby Extendoffice 20160922
    Dim xRow As Long
    Dim VInSertNum As Variant
    xRow = 26
    Application.ScreenUpdating = False
    Do While (Cells(xRow, "A") <> "")
        VInSertNum = Cells(xRow, "K")
        If ((VInSertNum > 1) And IsNumeric(VInSertNum)) Then
           Range(Cells(xRow, "A"), Cells(xRow, "K")).Copy
           Range(Cells(xRow + 1, "A"), Cells(xRow + VInSertNum - 1, "K")).Select
           Selection.Insert Shift:=xlDown
           xRow = xRow + VInSertNum - 1
        End If
        xRow = xRow + 1
    Loop
    Application.ScreenUpdating = False
End Sub
