title: FullSeriesCollection issues
body: <p>I am using the following code to plot a graph:</p>
  
  <pre><code>Set Date_Rng = range("Time_Series_Dates_1")
  
  Set Rng_1 = range("Time_Series_1")
  Sheet10.ChartObjects("Chart 2").Activate
  With ActiveChart
    .SeriesCollection.Add Source:=Rng_1
     .ChartType = xlLineMarkers
    .Axes(xlCategory, xlPrimary).HasTitle = True
    .Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "Dates"
    .Axes(xlValue, xlPrimary).HasTitle = True
    .Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "£ GDP"
    .Axes(xlCategory).HasMajorGridlines = True
    .SeriesCollection(1).Format.Line.ForeColor.RGB = RGB(255, 0, 0)
    .SeriesCollection(1).XValues = Date_Rng
   End With  
  </code></pre>
  
  <p>I am then trying to do the following:</p>
  
  <pre><code>           Selection.Formula = _
      "=SERIES(,'Tool v13.xlsm'!Time_Series_Dates_1,'Tool v13.xlsm'!Time_Series_1,1)"
  </code></pre>
  
  <p>and I get an object-defined error! What am I doing wrong please?
   I have tried this:</p>
  
  <pre><code>  With ActiveChart
     .SeriesCollection.NewSeries
     .FullSeriesCollection(1).Values = _
      "=='Tool v13.xlsm'!Time_Series_1"
  
     .ChartType = xlLineMarkers
    .Axes(xlCategory, xlPrimary).HasTitle = True
    .Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "Dates"
    .Axes(xlValue, xlPrimary).HasTitle = True
    .Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "£ GDP"
    .Axes(xlCategory).HasMajorGridlines = True
    .SeriesCollection(1).Format.Line.ForeColor.RGB = RGB(255, 0, 0)
    .SeriesCollection(1).XValues = Date_Rng
   End With
  </code></pre>
  
  <p>But no luck. Could there be anything wrong with my named range?</p>
