Hide Pivot Table Items By Condition

I copied and modified the pivottable code from http://www.ozgrid.com/VBA/hide-pivot-fields.htm. I am getting a "Run time 13" error on the line I colored purple. I tried removing different "Dim" statements to make it work and I'm having no luck.

Sub PickUpPivotTable()
Dim pt As PivotTable, pi As PivotItem
Dim lType As Long, lHarn As Long
Dim strCri As String, strCri1 As String, strCri2 As String
Dim bHide As Boolean
Dim xlCalc As XlCalculation
Set pt = Worksheets("Monthly Pivot Summary").PivotTables("MonthlyPivotSummary")
strCri = "P/U"
For Each pi In pt.PivotFields("Type").PivotItems
lType = pi..........................
