I thought I had this working, but due to an intermittently faulty
anemometer some of the output has N/A instead of 0:

This causes problems with WXSim-Lite which can't read the file properly and
crashes. I thought this would be an easy fix by using the 'is not None' to
test for data in $windDir. My template looks like this (the new bit in
bold):
#encoding UTF-8
#errorCatcher Echo
## +----------------------------------------------------+
## | Cumulus Monthly Output Template |
## +----------------------------------------------------+
## | Produces a YYmmlog.txt output for import to WXSim |
## +----------------------------------------------------+
#set $rainacc = $year.rain.sum.raw - $month.rain.sum.raw
#set $dayrainacc = 0
#set $daycount = 1
#set $wndspd = 0
#set $wnddir = 0
#set $wndgst = 0
#set $wndchl = 0
#for $record in $month.records
#set $rainacc = round($rainacc + $record.rain.raw,1)
#set $dayrainacc = round($dayrainacc + $record.rain.raw,1)
#set $daycount = $daycount + 1
#if $daycount == 289
#set $daycount = 1
#set $dayrainacc = round($record.rain.raw,1)
#end if

#end for
When the report runs I get the error: 'ValueHelper' object is not callable.
Any ideas? I'm not sure where the ValueHelper object is. I tried #if
$record.windDir.raw != 'N/A' but got the same error.
Any ideas how I can test for N/A in the records?
