Addin text scroller to text filed

hey guys,

im trying to add a scrollbar to a text field

when i drag the scrolbar from the componets onto the text field in a new movie it works ok.

however the exisiting movie im trying to modify wont have a bar of it.

i have the text box set as dynamic text etc… when i drag the scrollbar onto the field it doesnt automatically position…

any ideas?

cheers
