Please help!

hi!
I am trying to make some buttons that play different parts of multiple movie clips- and also link to a url. I also want to be able to click on a movie clip and make it play starting from a certain point (this is what I have been working on) I have this code

stop();
_root.frogdance.stop();
froggy.onRelease = function() {
_root.frogdance.play(4);
}

it is on an actions layer of my main timline- I am not sure if I put it in the wrong place or what- but it doesn’t do ANYTHING when I click on it when testing the movie. I gave the frogdance movie clip the instance name ‘froggy’ in the properties panel. The rest of what I am working with will be buttons that do things- but I also want this movie clip thing to work…

I am new to this so please be patient! I can show you the file if I am being confusing. I’ve been trying to get this to work for a couple days! please help

thanks!
