Problem w/ Headlab News Flasher V1.1.2

this is my problem:
http://www.kirupa.com/developer/mx/newsflasher.htm

i am trying to get the newsticker to work, but have no luck ajusting the area where you can see the text.
i tried millions of numbers in the “xwidth of animation field”, but the ticker is always flying in/out the whole page???

my stage is 800 in width and the area where i want the ticker to “see through” is 650 wide…

it is driving me crazy … any ideas on this one?
thanx in advance
