AICC posting problem [Error=1]

I've always had a problem with Lectora and LearningSpace... tested with Lectora 2003 and Lectora 2004 and all service packs in between. I have not had a copy of 2005 to test with.Here's the problem:adding custom variables that fall under [CORE_LESSON] creates a problem in the aicc_data string and LearningSpace returns [ERROR=1]. If we do not have any custom variables and Lectora only posts [CORE] data, it tracks properly and returns [ERROR=0]. ExitAU command also returns [ERROR=0].The only thing I can think of is the trailing linebreak it adds after the audioEnabled variable. Don't think this should cause a problem... but LS doesn't seem to agree with it.Here is the exact post from the debug output:Sending [PutParam] to [http://www.ourLMSserver.com/LearningSpace5/Program/Scripts/Track.asp][CORE]time=00:05:39lesson_location=a001_introduction.htmlscore=100lesson_status=P[CORE_LESSON]VaraudioEnabled=1***end of data***com.ms.security.PolicyEngine ... assertPermission ...
