RE: Dance Script

Okay I found this script but not sure how to amke it work I did replace the dances with some of my own. So could someone tell me why all I do is sit and it does not work. I am new at this scripting. So please forgive my stupidness.
// remove this number for the script to work.

list dances = [ "Club Dance 4","Crazy Side Step Dance", "Do The Monkey", "Foot Shuffle Dance", "You Spin Me Right Round Dance" ];
integer WHICH = 0;
integer TOTAL = 5;
integer PERMS = 0;
integer ON = FALSE;

default
{
state_entry()
{
llRequestPermissions(llGetOwner(), PERMISSION_TRIGGER_ANIMATION);
llSetTimerEvent(1.0);
llListen(0, "", llGetOwner(), "";
}

timer()
{
PERMS = llGetPermissions();
if (PERMS & PERMISSION_TRIGGER_ANIMATION)
{
if (ON == TRUE)
{
llStopAnimation(llList2String(dances, WHICH - 1));
llStartAnimation(llList2String(dances, WHICH));
WHICH++;
if (WHICH >= TOTAL)
{
WHICH = 0;
}
} else if (ON == 2)
{
llStopAnimation(llList2String(dances, WHICH - 1));
WHICH = (integer)llFrand(TOTAL + 0.999);
llStartAnimation(llList2String(dances, WHICH));
}
}
}

listen(integer channel, string name, key id, string message)
{
if (channel == 0 && id == llGetOwner())
{
if (message == "doff"
{
ON = FALSE;
} else if (ON == FALSE && message == "don"
{
if (!(PERMS & PERMISSION_TRIGGER_ANIMATION))
{
llRequestPermissions(llGetOwner(), PERMISSION_TRIGGER_ANIMATION);
}
ON = TRUE;
} else if (ON == FALSE && message == "dancer"
{
if (!(PERMS & PERMISSION_TRIGGER_ANIMATION))
{
llRequestPermissions(llGetOwner(), PERMISSION_TRIGGER_ANIMATION);
}
ON = 2;
}
}
}
