Code won't work after Deleting Keyframes?

Hi,
I’ve been having a problem with disappearing arrow buttons and my picture rollovers. On my main scene everthing is placed in the first keyframe but I noticed that there were empty keyframes following so I deleted them. Now when I go to test the website, none of my code works when the buttons are clicked, although all of the code is still there in my actions layer on the main timeline. Please help?!
Thanks,
