Score doesn't pass to LMS [WebTutor Mobile]

I have a trouble with passing score to LMS [WebTutor Mobile]. The point is LMS gets status information [passed/inprocess], but it doesn't get score data. But everithing goes perfect within their desktop LMS version [Websoft HCM]

 

I use this JS code on my last slide:

var p = GetPlayer();
var f = p.GetVar("final");
lmsAPI.SetScore(f,100,0);

lmsAPI.SetReachedEnd();
lmsAPI.SetPassed();
lmsAPI.CommitData();

 

WebSoft's support tested one of my course and they said it needs to find out why the course doesn't pass data during running within iframe

 

Anybody had this kind of problem?)
