Yet another Storyline Javascript email help request

I have read through the JS examples.

I've searched and read many of the JS Email related posts in the forums - and made sure testing was done on a web server or LMS (not local) and a Flash (not HTML5) version - as suggested in some posts.

And still, I can't get the JS code to work. It simply won't launch.

There is one thing I am not sure about and saw a mention in one of the posts. What happens if one or more of the variables I try to get from the player is empty - i.e. Tthe learner did not fill it in (this is possible in the flow). Will that prevent that JS from working properly?

If not - what might be the problem with the code?

If yes - is there a suggested workaround (as in some cases I need the variable to remain empty).

var player = GetPlayer();
var need = player.GetVar("NeedDevelop");
var important = player.GetVar("Importent");
var activity1 = player.GetVar("SubActiv");
var activity2 = player.GetVar("SubActiv02");
var activity3 = player.GetVar("SubActiv03");
var activity4 = player.GetVar("SubActiv04");
var activity5 = player.GetVar("SubActiv05");
var activity6 = player.GetVar("SubActiv06");
var activity7 = player.GetVar("SubActiv07");
var activity8 = player.GetVar("SubActiv08");
var activity9 = player.GetVar("SubActiv09");
var notes1 = player.GetVar("Implemented01");
var notes2 = player.GetVar("Implemented02");
var notes3 = player.GetVar("Implemented03");
var notes4 = player.GetVar("Implemented04");
var notes5 = player.GetVar("Implemented05");
var notes6 = player.GetVar("Implemented06");
var notes7 = player.GetVar("Implemented07");
var notes8 = player.GetVar("Implemented08");
var notes9 = player.GetVar("Implemented09");
var resources = player.GetVar("Resources");
var timeframe = player.GetVar("WhenActivity");
var evaluate = player.GetVar("HowActivityHelps");
var support = player.GetVar("HelpFromOthers");
