HELP : MouseClick + KeyDown function

Hello there,

I was hoping that I could put a hidden button on my movie. I found this code over the internet but it seems not to work. Can someone help me with this?

breadcrumbs_btn.onRelease = function() {
if (Key.isDown(99)) {
getURL(“http://www.mysite.com/mypage.php”, “_self”);
}
};

99 is the keycode for letter c by the day

thank you so much
