Dynamic scroller in mx professional?

i know this is probably really basic but i can’t get the dynamic scroller to work in mx 2004 pro version…

the only thing i can see that’s different from my file to the kirupa sample file is that the parameters of the scroller component are set to “_targetIntancename” rather than “Target TextField”…

any ideas? this is the error:

Warning Scene=Scene 1, layer=Layer 1, frame=1:Line 1: The identifier ‘loadVars’ will not resolve to built-in object ‘LoadVars’ at runtime.
loadText = new loadVars();

sorry i’m not that savvy with action script… any help would be great…
