Python to select page name and export current page using data driven pages

I am creating a thematic mapbook in Python using some arcpy.mapping functions.  One map in the mapbook is a section map which utilizes data driven pages.  I would like the user defined parameter string of the section, township, range to be used to get to the correct data driven page.  Then I want to export only the current page to PDF.  The index field in the data driven pages is called SEC_FULL.  This is also the field used to name the pages.   I am getting stuck on how to write this in Python.  Here's what I have so far which does export the map as a PDF, but it is the wrong page. It is not finding the correct page from the user defined parameter.

#Import arcpy module
import string
import arcpy
import os
from arcpy import mapping
from os import sep as bs

# Script arguments
STR = arcpy.GetParameterAsText(0)

#Export Section Map
mxd = arcpy.mapping.MapDocument(r"V:\gislu\Planning\DeveloperKit\SectionMap.mxd")
df = mapping.ListDataFrames(mxd, "STR Map")[0]
ddp = mxd.dataDrivenPages
Layer = mapping.ListLayers(mxd, "Section Lines", df)[0]
clause = "\"SEC_FULL\" = '" + STR + "'"
arcpy.AddMessage("SELECTING: " + clause)
arcpy.SelectLayerByAttribute_management(Layer, "NEW_SELECTION", clause)
df.scale = 9300
pageID = ddp.getPageIDFromName("SEC_FULL")
ddp.currentPageID = pageID
tmpPdf = r"V:\gislu\Planning\DeveloperKit\output\Section_temp.pdf"
ddp.exportToPDF(tmpPdf, 'CURRENT', resolution = 175)
del mxd, tmpPdf
