Can anyone help me to solve this coding?

[heeromai]

on (press) {
myTextArray = new Array();
myTextArray = (myInputText.split(" "));

for (var i = 0; i < myTextArray.length; i++)
{
if (myTextArray[i] == "welcome")
_root.firstSound.start();

if (myTextArray[i] == "my")
_root.secondSound.start();

}
