don't quote on me, but I think this is what it is saying...
var BAR_SIZE:Array = [Music, Recording, DMBSearch] Value) width
Assign the Variable BAR_SIZE to an array in which the:
Music, Recording, DMBSEARCH all have the value of Value as their width.
likewise...
var BAR_SIZE_PIVOT:Array = [Music, Recording, DMBSearch] Value) width
Just a guess...
