Hello I'm trying to make a loop to edit all the graphs in a workbook. There's a variety of charts with 1, 2, 3 or 4 bars. I want to go through and make all the 1st bars one colour, 2nd bars another etc. I've tried to make a loop (very new to VBA), below, but it fails whenever it gets to a chart with less than 4 bars because it says the 'parameter is not valid'.

How do I edit the below to ignore the FullSeriesCollections is they are not present in the active chart?

Sub ColourChange()

Dim sht As Worksheet
Dim CurrentSheet As Worksheet
Dim cht As ChartObject

Application.ScreenUpdating = False
Application.EnableEvents = False

Set CurrentSheet = ActiveSheet

For Each sht In ActiveWorkbook.Worksheets
For Each cht In sht.ChartObjects
cht.Activate

ActiveChart.FullSeriesCollection(1).Select
With Selection.Format.Fill
.Visible = msoTrue
.ForeColor.RGB = RGB(0, 176, 80)
.Transparency = 0
.Solid
End With
ActiveChart.FullSeriesCollection(2).Select
With Selection.Format.Fill
.Visible = msoTrue
.ForeColor.Brightness = RGB(192, 192, 0)
.Transparency = 0
.Solid
End With
ActiveChart.FullSeriesCollection(3).Select
With Selection.Format.Fill
.Visible = msoTrue
.ForeColor.RGB = RGB(192, 0, 0)
.Transparency = 0
.Solid
End With
ActiveChart.FullSeriesCollection(4).Select
With Selection.Format.Fill
.Visible = msoTrue
.ForeColor.RGB = RGB(192, 0, 192)
.Transparency = 0
.Solid
End With

Next cht
Next sht

CurrentSheet.Activate
Application.EnableEvents = True

End Sub

Thanks
