I fully understood the smooth transitions tut but I also need to make sub-sections within each section. Do I need to to make a new container mc on the section to pull up the subsection? Must I remove the (_root) to place it on a level? I have the source files to demonstrate what I tried doing. Section 1 has a button that needs to go to “sub_section1.swf”.
is the subsection under button one an external movie?? 
Yes, section1 is calling on another external movie (named sub_section1) with same characteristics/transisitons.
