Textboxes and flash

hi im using a text box in flash the text box contains a scrollbar (vertical one) which works fine. I would like to add hyperlinked text into the text box aswell as text of different color, the way i tried to do it was to create the text in separate text boxes and position it inside the textbox with the scroll bar. BUT i found that the text doesnt move in accordance to the scrolling.

How can i put hyperlinked text/text of different colour or font all in one text box with a scrollbar

hope u can help thanks in advance
