getting NaN errors with aicc + ajax

I run an LMS that supports AICC, and we have always run Lectora courses this way. That uses Java, of course. Once the version came out that uses Ajax instead of Java (2006?) the Ajax communication errors out when trying to set the elapsed time, because it sends the time as NaNNaN:NaNNaN:NaNNaN, which of course means not-a-number. So somewhere betweem the initial GetParam and the very next PutParam, my integers are getting hosed. I have tried tweaking the getparam function the best I can, but I have very little in the way of debugable output to work with. Any help is greatly appreciated. I'm sure anyone who knows about this will want to see some files, and I have all the files.. just let me know what you want (didn't want to be presumptuous and post them all). I case it matters, I can ask my customers (the ones making the courses) to uncheck the "use javascript" box to revert back to Java, and it will work fine. That does not mean there is necessarily an error in the Ajax, but it is obviously more touchy in some subtle way.I run an LMS that supports AICC, and we have always run Lectora courses this way.
