Always get error "Testing was interrupted and results are incomplete"

[LaxmikantChitare]

I have created a PythonTest wiki page in FitNesse with the following contents:

!contents -R2 -g -p -f -h

!define TEST_SYSTEM {slim}
!path C:\Python26\Lib\site-packages\waferslim-1.0.2-py2.6.egg\waferslim
!define COMMAND_PATTERN {python -m waferslim.server --syspath %p -v -k -l "C:\config\logconfigTemp.ini"}

|import|
|waferslim.fixtures|

|script|echo fixture|
|$value_1=|echo|9|
|$value_2=|echo|11|

|import|
|waferslim.examples.helper_fixtures|

|DT:multiplication|
|value 1|value 2|result?|
|$value_1|$value_2|99|

When I save the page and hit Test, I get this error:
Testing was interrupted and results are incomplete. Test Pages: 0 right, 0 wrong, 0 ignored, 0 exceptions Assertions: 0 right, 0 wrong, 0 ignored, 0 exceptions (0.646 seconds)

When I click on the "Errors Occured" button, I see:

slim:fitnesse.slim.SlimService
