Error #1009: Cannot access a property or method of a null object reference. at FtScrollBar/checkSize() at FtScrollBar/LwJIyBI91212G2rSD7M351()

I need to figure this out I am not that nw to flash but fairly new in action script, I basically got this code from a forum so is not that I actually understand it that much. Hopefully is in the code and not in the scroll bar component am using.

I am attaching my files.
1. Pelicula_page.sfw is the file I need to fix, problem seems to be on scene 3, soon it can also be on scene 2 I just have not added the scroll bar component there yet.
2. The other folder is for you to install the component on your machine other wise you wont be able to see my scroll bar. Note: Change the following files extension from FtScrollBarAS3.txt to FtScrollBarAS3.mxp and install, pelicula_page.txt to pelicula_page.fla, ScrollBarAssets_1.txt to ScrollBarAssets_1.fla, ScrollBarAssets_2.txt to ScrollBarAssets_2.fla, sample.txt to sample.swf and sample.jpg to sample.fla.

You probably need just these 2 files only FtScrollBarAS3.txt to FtScrollBarAS3.mxp and install, pelicula_page.txt to pelicula_page.fla, the rest are scroll bar samples.

Problem happens once you click on the sub buttons called Edmundo Rodriguez ect.. and try to go back to example Luis H. Collazo, scroll bar stops working. It works the first time clicked but not the second time clicked.

The rest of the content is not finish yet but all buttons under the equipo de produccion ( production team bios) will have small bios that will required bios.

I use this component because I did not know how to do a scroll bar that will scroll a movie clip like the one I did that used many fonts and a picture at the same time.

This is a movie website am working on, and is due Friday for first try.
Any Help will be appreciated.

dont' use scenes.
scenes more often than not result in odd things happening.

Problem solved! Scroll Bar plus text field need it to be in their own movie clip.
