HELP!python select records and export map2PDF

I am creating a tool in python that will automate (essentially) the following process:

Find the first layer in the map document (which is the parcelLayer)
Create a feature layer from this layer so that it can be selected
Get a cursor to go thru the table and find the parcel number field "APN_NU_1"
For each parcel number, select the parcel and export the map to a pdf
Repeat until there are no more records to go thru.

My script seems to be successfully iterating thru the records fine, but the pdf is not displaying the selection on the selected parcel boundary.  In other words, the parcel that is selected should be highlighted on the map and then exported to pdf.

What am I missing?  I have provided the code in the text and have also attached the map document and geodatabase.  My parcel feature class (for testing) only has two records, fyi.

#import modules and define workspace import arcpy import os import traceback  workspace = arcpy.env.workspace = r"C:/temp" print workspace   arcpy.env.overwriteOutput = True  #Define map document mxDoc = arcpy.mapping.MapDocument(r"C:/temp/PSL_Parcel.mxd") print mxDoc  #List the first dataframe (named Layers) in the map document df = arcpy.mapping.ListDataFrames(mxDoc, "Layers") [0]   #List first map layer (which is the parcels layer) in dataframe parcelLayer = arcpy.mapping.ListLayers(mxDoc,"",df) [0] print parcelLayer parcelField = "APN_NU_1"  #Create a feature layer to make selections on selectingLayer = arcpy.MakeFeatureLayer_management(parcelLayer, "parcelLayer_lyr")   #Set up cursor: rows = arcpy.SearchCursor(selectingLayer)  recordsCounted = 0  #Find the field, select each record and get values  for row in rows:     APN = row.getValue(parcelField)     whereClause = "APN_NU_1 = '%s'" % APN, "NEW_SELECTION", whereClause)     print row.getValue(parcelField)        recordsCounted += 1       #Export map with selected record to PDF     pdfLocation = 'C:\\temp\\'          pdfName = pdfLocation + APN + '.pdf'          arcpy.mapping.ExportToPDF(mxDoc, pdfName)        print recordsCounted                               del row, rows   #Clean up feature layers from memory and to debug and or rerun script arcpy.Delete_management(selectingLayer)     

Thanks in advance for your help,

PS.  I was only able to attach a .zip containing the shapefile for the parcels, rather than the geodatabase and feature class.  So, the path for this would have to change in the script and you would have to add it to the map as the first layer in the TOC.  Also, save all to C:/temp!
