Simple Flash Dropdown Menu - Action Script

Good Afternoon All,

I am working on a tutorial for a simple dropdown menu in flash.

I've got the buttons all taken care of but I'm getting errors in the Actionscript

Here is the first script:

on(rollOver) {
gotoAndStop("open");
}

"open" being a label

The second script is:

on(rollOver) {
    gotoAndStop("closed");
}

The error I'm getting is: 1087: Syntax error: extra characters found after end of program.
