compiler doesn't understand data type in array

[aytURont]

I loaded sounds into an array using:
function soundLoadComplete(event:Event):void {
soundsArray.push(sound);
soundLoadCount +=1;
if (soundLoadCount > maxSounds) {
sound.removeEventListener(ProgressEvent.PROGRESS, soundProgressHandler);
sound.removeEventListener(Event.COMPLETE, soundLoadComplete);
sound.removeEventListener(IOErrorEvent.IO_ERROR, soundLoadFailure);
playTheSoundForReal();
} else {// load the next sound file
soundRetrieveNext();
}
}

In checking the contents of the array at runtime, the array elements are of type flash.media.Sound

To play the sounds, the line is:
soundChannel = soundsArray(nextSoundIndex-1).play();

In attempting to execute, I get the following compile error:
1180: Call to a possibly undefined method soundsArray.
