MC load if _currentframe==?

//this may confuse u so a better explanation is at the buttom, I think

I have a masked animation that needs to play before a mc is loaded. when the masked animation reaches a certain frame #, load an external movie into a container in a sperate MC. hope this makes sense, the code I am using for the button is as follows, but it won’t load the movie and I think it’s because the MC is actually on frame 10 then playes back to 1 so the current frame at the time the button is pushed would be 10 not one. How can I tell it to load once it does reach the desired frame#??

button.onRelease = function() {
bug = false;
//bug sets a previous function which plays the desired animation “mask”
if (mask._currentframe == 1){ container.loadMovie(“images/stsoho1.jpg”,1)};
};
