title: Matching "Casa" String with oSeries.name doesn't match in VBA
body: <p>This VBA code try to paint the "Casa" line in black colour:</p>
  
  <pre><code>Dim ActiveSheet As Worksheet
  Dim oChart As Chart
  Dim oSeries As Series
  
  Set ActiveSheet = Sheets("Gráficas")
  ActiveSheet.ChartObjects("Gráfico 200").Activate
  Set oChart = ActiveChart
  
  For numLine = 1 To oChart.SeriesCollection.Count
      Set oSeries = oChart.SeriesCollection(numLine)
      MsgBox oSeries.name
      If oSeries.name = "Casa" Then
          MsgBox "Success"
          oSeries.Format.Line.ForeColor.RGB = RGB(0, 0, 0)
      End If
  Next
  </code></pre>
  
  <p>But what happens is that I see the names of all lines in chart, including "Casa" but no Success message painted, nor line black painted.
  It seems that the String doesn't match... but why?</p>
