[Help] Message to all players through GUI

[devilsknite1]

What I'm trying to do here is make a chat system such as Maloria has. The box instead of the chat bar. I know I didn't disable the chat bar, there's a reason for that.

PHP Code:

//#CLIENTSIDE

function onCreated()
{
  new GuiWindowCtrl( "Opening_Window1" )
  {
    profile = GuiBlueWindowProfile;
    clientrelative = true;
    clientextent = "909,145";
    canmove = false;
    canresize = false;
    closequery = false;
    canclose = false;
    destroyonhide = false;
    canmaximize = false;
    canminimize = false;
    text = "Chat Box";
    y = 535;
    // Text Stuff
    new GuiTextEditCtrl( "Opening_TextEdit1" )
    {
      profile = GuiBlueTextEditProfile;
      height = 20;
      width = 795;
      y = 125;
      text = "Enter your message here then press send";
    }
    // Send Button
    new GuiButtonCtrl( "Opening_Button1" )
    {
      profile = GuiBlueButtonProfile;
      text = "Send";
      width = 54;
      x = 795;
      y = 115;
    }
    // Clear Button
    new GuiButtonCtrl( "Opening_Button2" )
    {
      profile = GuiBlueButtonProfile;
      text = "Clear";
      width = 59;
      x = 849;
      y = 115;
    }
    // Text Scroll
    new GuiScrollCtrl( "Opening_MultiLine1_Scroll" )
    {
      profile = GuiBlueScrollProfile;
      height = 113;
      hscrollbar = "dynamic";
      vscrollbar = "dynamic";
      width = 909;
      // Text
      new GuiMLTextCtrl( "Opening_MultiLine1" )
      {
        profile = GuiBlueMLTextProfile;
        height = 16;
        horizsizing = "width";
        text = "";
        width = 884;
      }
    }
  }
}

// Send Button
function Opening_Button1.onAction()
{
  if ( Opening_MultiLine1.text == "" )
  {
    Opening_MultiLine1.text = player.account @ ":" SPC Opening_TextEdit1.text;
    sleep( 0.05 );
    Opening_TextEdit1.text = "";
  }
    else
  {
    Opening_MultiLine1.text = Opening_MultiLine1.text NL player.account @ ":" SPC Opening_TextEdit1.text;
    sleep( 0.05 );
    Opening_TextEdit1.text = "";
  }
}

// Clear Button
function Opening_Button2.onAction()
{
  Opening_MultiLine1.text = "";
} 


If you can help out with this, thanks in advance.
