how do I store array item.count from xml into js?

hi everyone

I started studying a bit of javascript and first made a small task: store array item.count from the 'test' array into js variable.

Here's what I've tried:

html here:

and xml here:
http://vt.most-inform.com/bugs/array/tour.xml[/size]

I added 'onready' event to 'embedpano' action inside html. Inside this action I try to get and store two variables = 'itemcount' and 'fov'. Fov works OK, but 'itemcount' alerts 'null'. However 'itemcount' variable in the xml is traced OK.

I am obviously being stupid here, but forgive me that, I've just started learming krpano-js interaction[size=10] ;-)[size=10]
