Trying to add 3 simple movieclips, yet they are disappearing?

I took on a small AS2 project, which I shouldn’t but did anyway. I know AS3, but AS2 is foreign.

I am trying to add 3 movieclips from the library, to the stage. Only the last one shows up, and the others disappear. Every time I do an attachMovie, the previous ones disappear… What is going on here please :frowning:

var soundOnOff:MovieClip;
var sfx:MovieClip;
var submitScore:MovieClip;
soundOnOff = attachMovie("SOUNDonOFF", "s1", 0, {_x:325, _y:555}); 
sfx = attachMovie("SOUNDEFFECTSonOFF", "s2", 0, {_x:352, _y:555});
submitScore = attachMovie("EXITBUTTON", "s3", 0, {_x:379, _y:555});

All 3 should show up side by side. If I remove the last line of code, the middle one shows up (visibly added to stage). If I remove the middle line of code, and the last line of code, the first one shows up fine. 2 will not show up together, let alone all 3.

ty in advance:angel:
