Need help with something simple.

So I know this may sound silly but how would I make the player chat bar come up when pressing the "ChatButton"

NPC Code:

---

//#CLIENTSIDE

function onCreated() {

  new GuiBitmapCtrl("ChatButton") {

    profile = GuiDefaultProfile;

    bitmap = "gui-button.png";

    height = 57;

    width = 63;

    x = 27;

    y = 171;

  }

  function ChatButton.onMouseDown() {



}

}
