VBA Excel Sort dynamically HELP

[tryharder1997]

Hi, I'm fairly new to writing code and trying to write a macro that will sort my pivot table by either a month, or by a subtotal for a group. The months are just grouping for days and these months also fall into another grouping done by adding another row field not grouping in the pivot table. The only issue is that sometimes the data in pivot table changes so using the pivotline(#) reference is hard.

Sub macro5()'


    Sheets("Pivot").Select
Dim score As Integer
score = Range("B1").Value
If score = "0" Then
    ActiveSheet.PivotTables("PivotTable1").PivotFields("Sold to #").AutoSort _
        xlDescending, "YTD-2018-NOV"
Else
    ActiveSheet.PivotTables("PivotTable1").PivotFields("Billed to #").AutoSort _
        xlDescending, "YTD-2018-NOV"
End If
    Sheets("Report").Select
End Sub

This is the pivot lines code, but would rather i referred to the name of a column sort of like in GetPivotData.

Sub Macro4()
'
' Macro4 Macro
'


'
    Sheets("Pivot").Select
Dim score As Integer
score = Range("B1").Value
If score = "0" Then
   Application.CutCopyMode = False
    ActiveSheet.PivotTables("PivotTable1").PivotFields("Billed to #").AutoSort _
        xlDescending, "Sum of CUR", ActiveSheet.PivotTables("PivotTable1"). _
        PivotColumnAxis.PivotLines(19), 1
Else
      Application.CutCopyMode = False
    ActiveSheet.PivotTables("PivotTable1").PivotFields("Billed to #").AutoSort _
        xlDescending, "Sum of CUR", ActiveSheet.PivotTables("PivotTable1"). _
        PivotColumnAxis.PivotLines(20), 1
End If
    Sheets("Report").Select
End Sub

any help is much appreciated.
