[FMX]What is wrong with my code

[dboers]

I have 5 buttons and an mc with 5 text mc’s embedded after press 1 of the buttons the text mc should go in a certain y direction. This is my script:

function moveText(y) {
 text_mc.onEnterFrame = function() {
  this._y += (y-this._y)/5;
 };
}
function setBut() {
 for (var i in this) {
  if (this*._name.substr(0, 4) == "btn_") {
   this*.onRelease = function() {
	moveText(-this**200);
   };
  }
 }
}

But that is only working with one button. What am i doing wrong?
