We don't have the ability to search on our forum, unfortunately. It's something we need to add, but haven't found the time to yet. There are, however, no posts dealing with SumTotal.
What SCORM versions does your LMS support? Are you exporting your course in the right version? Many LMSs only support SCORM 1.2, and the myUdutu exports to SCORM 2004 by default. You can change this through the course editor.
If your problem persists, I would be happy to investigate your LMS further. I will need access to you installation to help out, though. Contact me directly at knoesgaard@udutu.com if you can't get it working.
