I have a symbol with a stop on its first frame and a stop on the playback control on the timeline, yet it plays before triggered.
It's a symbol that I want to play on rollover.
Also is it possible to add click or rollover code on the timeline, or does the code have to go on the element itself?
Is the symbol set to autoplay?
Check here, if it is uncheck it.
And you can add click or mouseover code to the timeline not just elements themselves, For example you can add a trigger on the timeline and when it hits that certain point play something from a different symbol etc.
For mouseover/rollover code
