Custom log file is malfunctioning

The example customtext.txt has these 3 tags in it:
%temp% %hum% %wind%

And after WD gets through with the customtext.txt file and creates customtextout.txt it produces:

Looks like the customtext.txt file has a misnomer. There isn’t a %wind% tag. Hmmm…

%windspd% i think it is
and the appending is working now greg, in another thrread you said it was not…

Brian, I didn’t say it wasn’t working I wanted to know how to use the option. I’m still confused. Where is the the custom log file? I looked in the logs directory and do not see any custom log file.
