It has been a while since I looked at this because the good people at QlikTech have now confirmed that it only works when users open the QVW files in the QlikView client software (anyone who opens the dashboard through the publisher site isn't logged with the script). This particular script uses (requires) some advanced permissions to make that logging happen, so you have to change the scripting engine security settings to make it work (and I suspect that is where you're getting your error). The module security needs to be set to system access and the current local security needs to allow system access. If you make these two changes, I suspect that will fix the problem (when you open the file, once those are set, it will ask you if you're sure you want it to have those access levels - you'll want to select yes or it won't work!
