Hi Rachel
SCORM 1.2 supports the SCORM 2004 standard except for the following areas
- Content Aggregation Model
- The Run-Time Environment
- Sequencing and Navigation
It sounds like the SCORM 2004 you have may be using these. If you have access to the original content in the authoring package then you could republish the package with the authoring tool to SCORM 1.2
Information is only passed one way from the SCORM to the LMS so what ever grades or status are passed to the LMS is what is used to judge whether the activity is completed. When a SCORM activity is submitted then this is an attempt - it is also possible to save progress in an attempt to restart this.
There are various settings for attempts and for troubleshooting SCORMS that may be helpful
Regards
