Loading movie clips inside a another movie

hi everyone.

i hope that you are all having a great morning and i would really like some help.

i have a scrollpane with some logos on, on top of these logos are button, when i have pressed the buttons i would like to action to load a new movie clip onto the main timeline to show more information on the logo clicked…basically on release i would like to show a movie clip on the stage, and when you click on another one of the logos i would like the last on to disappear and to be replaced by the other one.

if anyone could help me i would really appreciate it, cheers everyone.
