Determinators

Hi all
I've just finished rebuilding my server after serious hw failure.
I have xpl working, just can't find the script for recording temperature
from a TOM10.
I have followed these instructions:
To log the values of my temperature sensors I use a determinator. The
condition is a sensor.basic message with type=Temp. I then have an
action of
Type=Command
Target=TONYT-XQL.SCOOP (put your instance of TONYT-XQL here)
Schema=db.xql
Parameter Values
command=add
sql=select * from temperature
dateadded={SYS::DATE} {SYS::TIME}
name={XPL::DEVICE}
temperature={XPL::CURRENT}
But I get this in the error log
Sat 19/03/05 23:35:45 : Error executing action: :
System.NullReferenceException: Object reference not set to an instance
of an object.
at xPLHal.xplAction.Execute(XplMsg& xSource)
at xPLHal.DeterminatorAction.Execute(String ruleName, XplMsg&
xSource)
any ideas where I'm going wrong???
Thanks
Neil
