Embarrassed to Ask "droptarget"

programming flash
1

I attempted to follow the Computer/Paintbrush tutorial to create droptarget test. I am using CS4 Trial version. I can’t decide if I should purchase it or not. I used to create interactive modules for use in web-based courses but I have apparently lost my touch since I can’t get this to work.

I greatly appreciate any help. The code is below and the fla CS4 file is attached.

on (press) {
startDrag("_root.blackball");
}
on(release) {
stopDrag ();
if (_root.blackball._droptarget == “/bluedroptarget”) {
_root.bluedroptarget.gotoandStop(“yellow”);
}
}

Thanks for your time.
