Hi Josh,

Thanks for looking into this.  I commented out lines 85, 86, and 87 and =20=

it seems to have solved the TypeError problem.

The only possible snag for me is that I get a new error =20
(UnicodeEncodeError) when I try to access the string that's returned =20
from the operation.   The problem only occurs when I try to print the =20=

string stored in the variable "response" on line 14 of my test script.

Here's the test script I'm using to invoke the operation:

       1 #!/usr/bin/python
       2
       3 from IKEAMonkIndexService_services import *
       4
       5 import sys
       6
       7 loc =3D IKEAMonkIndexServiceLocator()
       8 # prints messages sent and recieved if tracefile is set
       9 kw =3D { 'tracefile' : sys.stdout }
      10
      11 port =3D loc.getIKEAMonkIndexServiceSOAPType(**kw)
      12 request =3D getDescriptionOfTheIKEAMonkIndexWrapper()
      13 response =3D =20
port.getDescriptionOfTheIKEAMonkIndexOperation(request)
      14 print response

Here's the output:

$ ./DescriptionOfTheIkeaMonkIndex.py

How much does it cost to buy McDonald=92s well-known Big Mac in a =
foreign =20
country, let=92s say in Sweden?  The solution is as easy as revealing. =20=

The Economist's Big Mac Index does not only give the cost of this basic =20=

food commodity in USD for a specific country.  It also provides an idea =20=

of the value of the particular country=92s currency and its overall =20
economic situation according to the theory of purchasing-power parity.  =20=

The cost of a local Big Mac is divided by the cost of a Big Mac in the =20=

US (in USD) resulting in the implied Purchasing Power Parity (PPP).  =20
Under(-) / over(+) valuation against the USD in percent indicates how =20=

the local currency are performing in comparison to USD. Under(-) / =20
over(+) valuation is calculated as [[[PPP - Exchange Rate]/Exchange =20
Rate] x 100].  (For further insight into the Economist's Big Mac index =20=

please follow this hyperlink: =20
http://www.economist.com/markets/bigmac/displayStory.cfm?=20
story_id=3D2708584)
Inspired by this, we have established the IKEA Monk Index as a Web =20
Service to provide the similar information, based on a bundle of IKEA =20=

commodities, to polyglots and IKEA lovers.  It will give you an idea of =20=

how expensive the furnishing of your next downtown apartment in =20
Stockholm, Paris or Berlin will be (in comparison to the US). Since =20
people have different views on the necessities needed to furnish a =20
room, we have chosen to base our index on a bundle of goods that =20
everybody will be able to agree on - the minimalist furnishing of a =20
monk=92s cell.  Less is more and all you need to possess in order to =20
furnish a room is a chair, a table and a bed. Thus, the IKEA Monk =20
Index. And the best thing of it all: in contrast to the Economist's Big =20=

Mac Index, the IKEA Monk Index is always up to date (it is updated each =20=

hour to reflect changing currency rates and any changes in prices in =20
the IKEA online catalogue).
This Web Service was established in the Fall of 2004 by three UC =20
Berkeley students (John Ward, Tobias Vogelgsang and Arne Alvern Baste) =20=

taking Adam Blum's class 'Web Services: Concepts, Design and =20
Implementation' at the School of Information Managment &amp; Systems.
When this description was fetched the current IKEA Monk Index was last =20=

updated at 22:29:40 on =20
2004-10-26.</descriptionOfTheIKEAMonkIndexResponse>
  </soapenv:Body>
</soapenv:Envelope>
Traceback (most recent call last):
   File "./DescriptionOfTheIkeaMonkIndex.py", line 14, in ?
     print response
UnicodeEncodeError: 'ascii' codec can't encode character '\u2019' in =20
position 57: ordinal not in range(128)

Has anyone else encountered this?  (I'm a newbie so it's possible that =20=

I'm missing something obvious.)

Any help is greatly appreciated.

Thanks!

John
