how do i control a flash object and makeing him play?

hallo everyone i have a flash object on the screen but it dosnt have an id or name so i just got it
like this: $("#containerdiv").find("obejct")
 
then i tried javascript flash function like Play() or Stop() but it pops up a warning that its not a function...
 
i also tried $("#containerdiv").find("embed") but that also didnt work.. it finds the object themselves but the .Play() or .Stop() dosnt work..
 
those anyone knows how i can do this?
 
thanks!
