I Hope There some bright heads out there

Need some help with basic flash! I’m probably to old for this ****…Nothing seems to work anymore:

Gotta do the following: Need to load external .swf into a mask…With a scroll-bar attached to it! HOW? And…if i load a external file without the mask, how can i decide where it shows up. It allways ends up in the upper left corner! I guess its probably some parametres i’ve missed? Most thankful for any suggestions!
