Pivot Table Conditional Formatting

Hi All,

I'm working with a pivot table and I'd like to keep the following conditional formatting in the "Sum of Variance" value field in column I:

Columns("I:I").Select

Selection.FormatConditions.AddColorScale ColorScaleType:=3
Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
Selection.FormatConditions(1).ColorScaleCriteria(1).Type = _
xlConditionValueNumber
Selection.FormatConditions(1).ColorScaleCriteria(1).Value = -0.5
With Selection.FormatConditions(1).ColorScaleCriteria(1).FormatColor
.Color = 8109667
.TintAndShade = 0
End With

Selection.FormatConditions(1).ColorScaleCriteria(2).Type = _
xlConditionValueNumber
Selection.FormatConditions(1).ColorScaleCriteria(2).Value = 0
With Selection.FormatConditions(1).ColorScaleCriteria(2).FormatColor
.ThemeColor = xlThemeColorDark1
.TintAndShade = 0
End With

Selection.FormatConditions(1).ColorScaleCriteria(3).Type = _
xlConditionValueNumber
Selection.FormatConditions(1).ColorScaleCriteria(3).Value = 0.5
With Selection.FormatConditions(1).ColorScaleCriteria(3).FormatColor
.Color = 7039480
.TintAndShade = 0
End With

Selection.Style = "Percent"

Having trouble maintaining the formatting though. It disappears with each refresh, slicer, filter and sort. What's the best method to maintaining this conditional formatting continuously?
