Request to Display "Unknown" Status Instead of "Failed" for Learner Outcomes

You'll need to set up a JavaScript trigger on the final slide with the appropriate conditions and the following piece of JS code:

var nFindAPITries = 0;
var API = null;
var maxTries = 500;

function ScanForAPI(win) {
  while (win.API_1484_11 == null && win.parent != null && win.parent != win) {
    nFindAPITries++;
    if (nFindAPITries > maxTries) {
      return null;
    }
    win = win.parent;
  }
  return win.API_1484_11;
}

function GetAPI(win) {
  if (win.parent != null && win.parent != win) {
    API = ScanForAPI(win.parent);
  }
  if (API == null && win.opener != null) {
    API = ScanForAPI(win.opener);
  }
}

var lmsAPI = GetAPI(this);

lmsAPI.SCORM2004_CallSetValue("cmi.completion_status", SCORM2004_UNKNOWN);
