First off you should style the script to get a better look on it.

I also think you cant use:

PHP Code:

if (player.chat == "Start") && if (player.guild == "Events Team") 


You can use two different ways:

PHP Code:

//first way:
if (player.chat == "Start") {
  if (player.guild == "Events Team") {
    //stuff
  }
}

//seccond way:
if (player.chat == "Start" && player.guild == "Events Team") {
  //stuff
} 


also the command

PHP Code:

message "bla" 


is GS1. In GS2 it is

PHP Code:

this.chat = "bla" 


Also at the part

PHP Code:

function onPlayerChats()
if (player.chat == "Start") && if (player.guild == "Events Team")
{ 


it should be

PHP Code:

function onPlayerChats() {
if (player.chat == "Start") && if (player.guild == "Events Team")
{ 


Here it´s a fixed version of yours:

PHP Code:

//#CLIENTSIDE
function onCreated() {
  this.image = "block.png";
}

function onPlayerChats() {
  if (player.guild == "Events Team") {
    if (player.chat == "Start") {
      this.chat = "3";
      sleep(1);
      this.chat = "2";
      sleep(1)
      this.chat = "1";
      sleep(1)
      this.chat = "";
      hide();
    }
    else
    if (player.chat == "Stop") {
      this.chat = "";
      show();
    }
  }
}
