Linking to external SCORM packages

Hi all,

I have a course with a navigation screen that learners will use to navigate to specific portions of the course. As each section is completed I want the system to record that section as having been completed. I'm using Simple SCORM Packager to combine multiple mini courses into one large course. The trouble I'm having is creating links to the other courses I've created.Each of the buttons on the attached screen shot I want to point to an external Articulate Presentation. I hope I'm being clear.  Any thoughts or suggestions?
