Roll over button problem ASAP

hi, i’m having a problem with my roll over sound

** heres whats up:** the sound plays the 1st time its rolledover but not second time.

** heres what i have:**
4 buttons with 4 sounds

** code: **

on frame #

///////Sound A///////
** _root.SchlubS = new Sound();
_root.SchlubS.attachSound(“Schlub01”);**
///////Sound B///////
** _root.CiavoS = new Sound();
_root.CiavoS.attachSound(“Ciavo01”);**
///////Sound C///////
** _root.ChimeS = new Sound();
_root.ChimeS.attachSound(“chime01”);**
///////Sound D///////
** _root.DoorbellS = new Sound();
_root.DoorbellS.attachSound(“Doorbell01”);**

on Button A,B,C,and D(just different names where (SchlubS) is)

///////Sound A///////
on (rollOver) {
if (_root.playing != 1) {
if (SchlubSPosition == null) {
SchlubSPosition = 0;
}
_root.SchlubS.start(schlubPosition, 0);
_root.playing = 1;
} else {
if (_root.playing == 1) {
SchlubSPosition = _root.SchlubS.position/1000;
_root.SchlubS.stop();
_root.playing = 0;
}
}
}

** what i want to happen:** when you roll ove Button A it plays untill you enter B,C, or D than that sound plays. but… i dont want C or D to loop, just A and B

Please help me , thank you
