Instance names

(I would put Flash CS3 in the title if I could :frowning: )

if you call an object several times in the timeline (i.e. in several keyframes), is it really required that you give each an instance name? Is there a way to apply a instance name to the object across the clip?

also… is this proper syntax? It doesn’t appear to be working
([“contentline” + _root.contentopen]).gotoAndPlay(“s1”);

it works in this…
gotoAndPlay([“content” + _root.contentopen + “-open”]);
