textField scrollPosition

has anyone used setting up of scroliPostion for a dynamic textField to the end of line? I have tried but i doesn’t seem to work. Nor it shows any error. Find the attachment please. - download the file - run the swf - use the input textfield to input - all you input will be displayed in a dynamic textfield to the right - when the input is more that dynamicField it don’t show the end of line. thats the trouble. then the check out the actions in frame 1
Thank you
