#Student grades reporting 0 in moodle when they submit scorm package update
This also means that if you update the SCORM package then the latest content will always be loaded (unless you update your core imsmanifest.xml file as this file is copied into Totara). This allows SCORM content to be hosted outside your Totara site and the content is played from the external location and is not unpacked/copied into Totara storage. If enabled and selected it provides a text field to paste a URL to a remote imsmanifest.xml (in an unzipped remote SCORM package). Try adding SCORM as an external package type. External package type is disabled by default on new installations it is not a great method of linking to packages as under certain circumstances your packages will not pass back any grade or tracking information to Totara Learn. If it does there may be something wrong with the settings on Totara.
To check if the problem is related to Totara or with the SCORM itself you can create an account on and upload the SCORM to see if it performs as expected.
