flash how to stop symbol animation with stop();

I have a main project. in it I have a movie symbol. The symbol is annimated to highlight itself. I've put a 2nd layer with a keyframe and the action script stop(); method. I went back the the main project and inserted the symbol on my timeline. my timeline is much longer then the symbols. I keeps looping the symbols timeline even though I put a stop in it. Basically I only want the symbol to play its animation once and thats the reason for the stop. I've tested the symbols annimation and the stop is working but from my main timeline it keeps looping. Any suggestions?

Also, If my main timeline is longer then the embedded swf it loops. I've tried putting keyframe and stop(); actions in the nested swf's timeline but it still loops. When I click the swf on my flash design console it does not display the loop options like a symbol does. This is where you can set it to play only once. I want the embedded swf to play once and stay at its last frame while the rest of my main timeline continues. Any ideas?
