I am just testing the Data Extract API and cannot get it to work even after watching the video and nearly copying the code word for word. What am I doing wrong?

My code:

import dataextract as tde

import csv,os,datetime

#Step 1: Create the extract file and open the .csv

try:

    tdefile = tde.Extract('APITest.tde')

except:

    os.remove('APITest.tde')

    tdefile = tde.Extract('APITest.tde')

csvReader = csv.reader(open('U:/Neil/Tableau/APITest.csv','rb'), delimiter=',',quotechar='"')

#Step 2: Create the tableDef

tableDef = tde.TableDefinition()

tableDef.addColumn('ID', tde.Type.CHAR_STRING)        #1

tableDef.addColumn('LOB', tde.Type.CHAR_STRING)         #2

tableDef.addColumn('GL Acct Num', tde.Type.CHAR_STRING) #3

tableDef.addColumn('CY YTD', tde.Type.DOUBLE)           #4

tableDef.addColumn('CY Audit ME', tde.Type.DOUBLE)      #5

tableDef.addColumn('CY Jan', tde.Type.DOUBLE)           #6

tableDef.addColumn('PY Jan', tde.Type.DOUBLE)           #7

tableDef.addColumn('PY Audit ME', tde.Type.DOUBLE)      #8

tableDef.addColumn('PY Dec', tde.Type.DOUBLE)           #9

tableDef.addColumn('PPY Jan', tde.Type.DOUBLE)          #10

tableDef.addColumn('PPY Audit ME', tde.Type.DOUBLE)     #11

tableDef.addColumn('PPY Dec', tde.Type.DOUBLE)          #12

#Step 3: Create the table in the image of the tableDef

table = tdefile.addTable('Extract',tableDef)

#Step 4: Loop through csv, grab data, put into rows, insert rows into table.

newrow = tde.Row(tableDef)

csvReader.next()

for line in csvReader:

    newrow.setCharString(0, str(line[0]))

    newrow.setCharString(1, str(line[1]))

    newrow.setCharString(2, str(line[2]))

    newrow.setDouble(3, float(line[3]))

    newrow.setDouble(4, float(line[4]))

    newrow.setDouble(5, float(line[5]))

    newrow.setDouble(6, float(line[6]))

    newrow.setDouble(7, float(line[7]))

    newrow.setDouble(8, float(line[8]))

    newrow.setDouble(9, float(line[9]))

    newrow.setDouble(10, float(line[10]))

    newrow.setDouble(11, float(line[11]))

    newrow.setDouble(12, float(line[12]))

    table.insert(newrow)

#Step 5: Close the tde

tdefile.close()

My error:

Traceback (most recent call last):

  File "C:/Python27/APIDataExtractTest.py", line 29, in <module>

    table = tdefile.addTable('Extract',tableDef)

  File "C:\Python27\lib\site-packages\dataextract\Base.py", line 484, in addTable

    raise Exceptions.TableauException(result, wstring_at(tablib.TabGetLastErrorMessage()))

TableauException: TableauException (303): duplicate table name

hello , I can't finish last task #step 2 :( tried many times and dont know what I'm doing wrong. the error is  as below

I found some answers in google but they dont help in my case. I know what the correct filter should be set up but the problem is that when I'm trying to search for the right filter -on the drop down list the option which I'm expected to see doesn't show . I dont know why.  On the dropdown there is no option "Volunteer Organization: Volunteer Organization Status"  or  "Volunteer Organization: Account Record Type"
