invalid use of null

Sep 17, 2008 at 12:40 AM
hey trying to use pal to anlayze some blg's.  i am using a customized threshold file (just gives a report on a handful of counters, and works on a smaller group of blg's).  when i try to load a bunch of blg's (140 in some cases) relog seems to compile everything, and then the script runs and fails with 'invalid use of null: 'cdate'' on, what i think, isline 4179.

im not very well versed in vbscript and thought someone may be able to shed some light for a newb.  thanks in advance!!!

Hi Wroc,
the problem seems due to a field inside the temporary file used by the script that could not be converted to a date and therefore produce a NULL result.
 I can bet that the reason is  one of the blg file is not converted or it is converted to an empty file beacouse it does not contain any data.
 So if this is the reason try this workaround:
 - convert manually al the blg file to csv using the relog *.blg -f CSV -o *.cvs
 - exclude the files that contains no data
 - redo the PAL analysis

Let me know your result 
PS if you are in trouble after the steps you can send me the zip of the blg ( if it is not too big )
