Is there anything wrong I am doing, or maybe missing something? I tried with different VAST testers online but it doesn't work firing one of the Viewable Impression (Viewable, NotViewable, ViewUndetermined) (the example.com/track/impression) not firing at all.
Code:

Any help would be much appreciated.
