Slider Menu Question

I did the tutorial and i got it to work, BUT…
i get an error as follows:

Scene=Scene 1, Layer=Slider, Frame=1: Line 1: Clip events are permitted only for movie clip instances
onClipEvent (load) {
Scene=Scene 1, Layer=Slider, Frame=1: Line 5: Clip events are permitted only for movie clip instances
onClipEvent (enterFrame) {

If anyone can explain what that means, I’d appreciate it! thnx!
