Pivot Table VBA

[chaddres]

I need to add a second filter to my pivot table. Right now, I have the "PI" filter and it works great. I'd like to add a second filter for the pivotfield "DOB" to be equal to the date in cell Z1. Any ideas?

'Overtime Check
    Sheets("Combined Time").Select
    Dim rng1 As Range
    Dim sht1 As Worksheet
    Dim pTable1 As PivotTable
    Set rng1 = ActiveSheet.Cells(1, 1).CurrentRegion
    Set sht1 = ActiveWorkbook.Worksheets.Add
    sht1.Name = "Overtime Pivot"
    Set pTable1 = ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
        rng1.Address, Version:=8).CreatePivotTable(TableDestination:= _
        sht1.Cells(1, 1), TableName:="PivotTable" & Format(Time, "hhmmss"))
    With pTable1
        With .PivotFields("DOB")
            .Orientation = xlPageField
        End With
        With .PivotFields("PR Code")
            .Orientation = xlPageField
            Dim PI As PivotItem
                 .EnableMultiplePageItems = True
            For Each PI In .PivotItems
                If PI = "9GK" Or PI = "9GL" Or PI = "9GM" Or PI = "9GP" Or PI = "9GQ" Or PI = "9GS" Or PI = "9J8" Or PI = "9J9" Or PI = "9JA" Or PI = "9JB" Or PI = "9JD" Or PI = "9JD" Or PI = "9JE" Or PI = "9JF" Or PI = "9JH" Or PI = "FLS" Or PI = "LE6" Or PI = "M2A" Or PI = "P40" Or PI = "V39" Then
                    PI.Visible = True
                Else
                    PI.Visible = False
                End If
            Next PI
        End With
        With .PivotFields("SSN")
            .Orientation = xlRowField
            .Subtotals(1) = False
        End With
        .PivotFields("Reg Hours").Orientation = xlDataField
    End With
