the target name is the name of the MovieClip that you want to perform the actoin.
/cheese is the name of the cheese MovieClip. tellTarget ("/cheese") is telling the MC cheese to perform the action. You define these names by giving the MovieClips Instance names in the Instance panel. CONTROL+I i believe…
if it is at the main level put _root. in front of the MC or if not then direct it to that level. If you are just doing something simple then you shouldn’t need to do anything more in depth than level1.
Yes its any MC. you just have to define the instance name.
