Subject: sensitivity analysis and Excel files

Hello to all,
I’m a phD student at the INRA Toulouse, and I’m currently trying to do some
sensitivity analysis with Cormas.
Description of the problem: just after defining the initial value, the final
value and the step value of the concerned parameter, I click on the “apply
and close” button. And then I obtain the following damned message:
“Unhandled exception: Message not understand: #value”.
When I try to debug, I see that the concerned method is “addClass: className
Attribut: attributName initPara: parameterInitialValue finalPara:
parameterFinalValue step: parameterStep” and especially its first line “self
classesToAnalyse at: className ifAbsentPut: Dictionary new”.
But after that, I can’t go further, my computing skills are largely
exceeded!
Last thing: this problem occurs with all the models and with all the
parameters. I believe I have the latest version of Cormas (Cormas2004
v.February, 28, 2005- 10:49:19 am). With this version, I successfully
exported my probes in Excel files. I tried the sensitivity analysis with an
older version (January 2005) and then it could be conducted but not with
Excel files.
What can I do to debug this?
Thank you in advance!
Regards,
Florent Arrignon
