Help making drop-down menus

Hey all,
I'm trying to make my first flash drop-down menu. I have Flash 6.0 i believe (yup, just checked) and I went through the tutorial which didn't help one bit. What I have so far is 2 key frames, each 20 frames long. The first frame is suppose to be my menu button when not active, the second frame is my button when the mouse is suppose to be over. I did convert both frames to buttons, but I'm confused as to how to code the frames (1) to detect OnMouseOver and or clicks move to the dropdown frame (2) downwards. Any tips or steps to do this? Just so you know I'm not sure on how to test my project. What I've been doing is clicking Play and it plays from frame 1-40 showing my 1 frame 20x and my 2nd frame 20x

Thx for any suggestions,
Spin

Never mind folks, I found my answer using the Reference guide that explains what the commands do. My biggest problem was not having the "On" option when I was workin with the frames. All I had to do was click the gray area outside of the work area and I could select the "On" function. Hope this helps anyone else.

I have another problem I can't find an answer to using the Help menu in Flash. How do you delete a Symbol name. I try to make a name for a symbol and it says its already used. I want to delete the old one and make a new one. Any Ideas?
