Error when setting Interior ColorIndex

[Glaswegian]

I'm sure there is an easy explanation for this, but I can't see it at the moment!
All I'm trying to do is clear some cells and change the interior colour based on the value of a Control Toolbox checkbox. However, I receive an error '1004 - unable to set ColorIndex property of Interior Class'. The code is so simple

Private Sub CheckBox1_Click()
Dim myRange As Range
Set myRange = Worksheets("Sheet7").Range("A1:D1")
If CheckBox1.Value = True Then
With myRange
.Interior.ColorIndex = 6
.Value = ""
End With
End If
End Sub

It works fine if I wrap the ColorIndex line in a single sub.

Sorry if this is a bit stupid but I'm stumped!

Thanks

Hi Iain ,

The problem is caused by the control taking focus.
Add the line to select a cell and all should be ok.

Private Sub CheckBox1_Click()
    Dim myRange As Range
    
    ActiveCell.Activate ' to take focus away from control
    
    Set myRange = Worksheets("Sheet1").Range("A1:C1")
    If Sheet1.CheckBox1.Value = True Then
        With myRange
            .Interior.ColorIndex = 6
            .Value = ""
        End With
    End If
End Sub

Of course!!

It's always the most obvious things that catch me out...

Many thanks.
