A SCORM package is usually a Zip archive. Any SCORM-compliant LMS that I have seen will usually have options to permit you to upload the zip file. Then the LMS will unzip it. You do not usually point the LMS at an HTM file. It usually wants to find the imsmanifest.xml file which should be at the root level of the zip file. This LMS file tells the LMS what the structure of the course is and therefore how to build the TOC for it.
I would check with your LMS admin to see if this is possible with your GEOMETRIX LMS.
