Accessing Storyline 2 variables from SCORMFunctions.js

Hi, I'm trying to custom javascript function "SCORM_RecordInteraction" in order to save interactions information in a specific way.

For that, I need to access course variables but I can't get the player like I do at normal js ("var player = GetPlayer();") so I can't get the variables either (var x = player.GetVar("varX")).

Can you help me with this??

Thank you very much,

Antonio.
